qemuxmlconftest: Add test cases for the new 'ps2' feature

Browse Source 
Introduce tests to verify that the 'ps2' feature is correctly parsed
when given either 'dirty' XML from a user or 'clean' canonical XML,
as produced by libvirt. This also tests the transformation from libvirt's
internal state to the aforementioned canonical form and to a QEMU
command line.

As a bonus, we also test some known bad configurations:
- When user explicitly adds ps2 bus inputs, but also explicitly disables
the 'ps2' feature.
- When user explicitly enables the 'vmport' feature, but also explicitly
disables the 'ps2' feature. This is not supported by QEMU and will
result in vmport device not being created without emitting any warning
or error.
