Fake capabilities are inserted twice, as in a few tests the architecture
is not present in the XML (testing filling in of the architecture).
Since we already know which architecture will be picked we don't need to
be adding the capabilities twice.
This doesn't impact the tests as they use the same approach to determine
the default arch.

And make callers check the return value as well. This helps error out early for
invalid environment variables.
That is desirable because it could lead to deadlocks. This can happen when
resetting logging after fork() reports translated errors because gettext
functions are not reentrant. Well, it is not limited to resetting logging after
fork(), it can be any translation at that phase, but parsing environment
variables is easy to make fail on purpose to show the result, it can also happen
just due to a typo.
Before this commit it is possible to deadlock the daemon on startup
with something like:
LIBVIRT_LOG_FILTERS='1:*' LIBVIRT_LOG_OUTPUTS=1:stdout libvirtd
where filters are used to enable more logging and hence make the race less rare
and outputs are set to invalid

to:
...

Under the qemucapabilitiesdata we have a replies file for

contains replies from a development snapshot release that
predates 3.0.0 (specifically it's v2.12.0-1689-g518d23a) and as
such does not reflect any change that was made to QEMU after the
snapshot and before the official relase. One of such changes was
renaming 'exit-preconfig' command to 'x-exit-preconfig' (QEMU
commit v3.0.0-rc1~21^2~3). Ideally, we would just regenerate
capabilities using the official release but since this is a PPC64

Set the kernel-hashes property on the sev-guest object if the config

having this setting off, it is not guaranteed to remain this way.
We can't assume that the QEMU capabilities were generated on an AMD host
with SEV, so we must force set the QEMU_CAPS_SEV_GUEST. This also means
that the 'sev' info in the qemuCaps struct might be NULL, but this is
harmless from POV of testing the CLI generator.

In the QEMU tests a test can either use an explicitly listed set of
capabilities, or can request those matching a particular QEMU
version. Sometimes it is desirable to be able to list extra caps

This is useful, for example, when QEMU won't report certain features
unless it was run on particular hardware or kernels, and those were
not used when a caps snapshot was imported to the libvirt source tree.
