The test was showing that the 'blockdev' capability is properly added
although we didn't detect it yet. Unfortunately this test can't be
carried over once we bump minimum qemu version to qemu-4.2.
Make the test case future-proof by removing the qemu-4.0.0 version which
would become pointless and use only already deprecated capability flags
so that the test output does not change.

Currently, a firmware configuration such as
<os firmware='efi'>
<firmware>
<feature enabled='yes' name='enrolled-keys'/>
</firmware>
</os>
will correctly pick a firmware that implements the Secure Boot
feature and initialize the NVRAM file so that it contains the
keys necessary to enforce the signing requirements. However, the
lack of a
<loader secure='yes'/>
element makes it possible for pflash writes to happen outside
of SMM mode. This means that the authenticated UEFI variables
where the keys are stored could potentially be overwritten by
malicious code running in the guest, thus making it possible to
circumvent Secure Boot.
To prevent that from happening, automatically turn on the
loader.secure feature whenever a firmware that implements Secure
Boot is chosen by the firmware autoselection logic. This is
identical to the way we already automatically enable SMM in such
a scenario.
Note that, while this is technically a guest-visible change, it
will not affect migration of existings VMs and will not prevent
legitimate guest code from running.

Generally speaking, when firmware autoselection is in use we
don't want any information to be provided manually. There are
two exceptions:
* we still want the path to the NVRAM file to be customizable;
* using <loader secure='yes'/> was how you would ask for a
firmware that implements the Secure Boot feature in the
original approach to firmware autoselection, so we want to
keep that working.
Anything else should result in a descriptive error.

This combination doesn't make sense and so the firmware
autoselection logic will not be able to find a suitable firmware,
but it's more user-friendly to report a detailed error upfront.
Note that this check would ideally happen in the validate phase,
but if we moved it there we would no longer be able to
automatically enable secure-boot when enrolled-keys=yes. Since
the combination never resulted in a working configuration, the
chances of this causing real-world VMs to disappear are
extremely low.

For finding the best matching CPU model for a given set of features
while we don't know the CPU signature (i.e., when computing a baseline
CPU model) we've been using a "shortest list of features" heuristics.
This works well if new CPU models are supersets of older models, but
that's not always the case. As a result it may actually select a new CPU
model as a baseline while removing some features from it to make it
compatible with older models. This is in general worse than using an old
CPU model with a bunch of added features as a guest OS or apps may crash
when using features that were disabled.
On the other hand we don't want to end up with a very old model which
would guarantee no disabled features as it could stop a guest OS or apps
from using some features provided by the CPU because they would not
expect them on such an old CPU.
This patch changes the heuristics to something in between. Enabled and
disabled features are counted separately so that a CPU model requiring
some features to be disabled looks worse than a model with fewer
disabled features even if its complete list of features is longer. The
penalty given for each additional disabled feature gets bigger to make
longer list of disabled features look even worse.
