[PATCH 17/48] qemu: Assume QEMU_CAPS_QUERY_CURRENT_MACHINE

[Michal Privoznik]

Introduced in QEMU's commit of v4.0.0-rc0~202^2~3 the
query-current-machine command is always available for all QEMU
versions we support (4.2.0, currently). Therefore, we can assume
the capability is always set and thus doesn't need to be checked
for.
