selftest: introduce QEMU_USE_KVM

The qemucommand.py script uses kvm-ok to determine whether KVM
is available. However, kvm-ok is very Ubuntu specific and not
readily available on Fedora.

Use QEMU_USE_KVM variable which is also used in OpenEmbedded
selftests. The variable must contain True to enable KVM for
machines containing x86 in its name, or contain a list of
machines. For meta-updater this makes sure KVM is used for all
tests:
QEMU_USE_KVM = "intel-corei7-64 qemux86-64"
