Subject: [PATCH] qemu: Don't check for /dev/kvm presence

The file being present doesn't necessarily mean anything these
days, as it's created independently of whether the kvm module
has been loaded[1]; moreover, we're already gathering all the
information we need through QMP, so poking the filesystem at
all is entirely unnecessary.
