As with the prior commit, prefer -cpu host for all guests (except when
we have more information from the source hypervisor). Although there
is the disadvantage that -cpu host is non-migratable, in practice it
would be very difficult to live migrate a host launched using direct
qemu commands.
Note that after this change, gcaps_arch_min_version is basically an
informational field. No output uses it, but it will appear in debug
output and there's the possibility we might use it for a future output
mode.
