[OE-core] [PATCH 1/1] testimage: fix boolean checking for QEMU_USE_KVM

[Chen Qi]

If QEMU_USE_KVM is set to a list of machines, when doing testimage
for a machine outside the list, we will get the following error.

  Exception: ValueError: Invalid boolean value 'intel-corei7-64 intel-core2-32 qemux86 qemux86-64'

This is because oe.types.boolean raises error if the parameter
is not values like 'true', 'false', etc.

Fix the boolean checking to avoid the exception.
