Since s390 does not support usb the default creation of a usb controller
for a domain should not occur.
Also adjust s390 test cases by removing usb device instances since
usb devices are no longer created by default for s390 the s390
test cases need to be adjusted.

Libvirt didn't prefix the random number generator backend object alias
with any string thus the device alias and object alias were identical.
To avoid possible problems, rename the alias for the backend object and
tweak tests to comply with the change.

On my machine, a guest fails to boot if it has a sound card, but not
graphical device/display is configured, because pulseaudio fails to
initialize since it can't access $HOME.
A workaround is removing the audio device, however on ARM boards there
isn't any option to do that, so -nographic always fails.
Set QEMU_AUDIO_DRV=none if no <graphics> are configured. Unfortunately
this has massive test suite fallout.
Add a qemu.conf parameter nographics_allow_host_audio, that if enabled
will pass through QEMU_AUDIO_DRV from sysconfig (similar to
vnc_allow_host_audio)
In the past we automatically added a USB controller and assigned
it a PCI address (0:0:1.2) even on machines without a PCI bus.
This didn't break machines with no PCI bus because the command
line for it is just '-usb', with no mention of the PCI bus.
The implicit IDE controller (reserved address 0:0:1.1) has
no command line at all.
Commit b33eb0dc removed the ability to reserve PCI addresses
on machines without a PCI bus. This made them stop working,
since there would always be the implicit USB controller.
Skip the reservation of addresses for these controllers when
there is no PCI bus, instead of failing.
