tests/qtest/test-x86-cpuid-compat: Check for machines before using them

Browse Source 
The user might have disabled the pc-i440fx machine type (or it's older
versions, like done in downstream RHEL) in the QEMU binary, so let's
better check whether the machine types are available before using them.
