[Libvir] PATCH: Added QEMU driver for virDomainGetOSType method

[Daniel P. Berrange]

For some reason we never had an impl of the virDomainGetOSType method for
the QEMU driver - and for even more bizarre reason it wasn't failing, because
the old libvirt.c code hardcoded 'linux' if there was no impl. The latter
was fixed by Rich, with the xenUnified driver, so exposing the former bug.
This patch adds a simple impl for QEMU - there's no need to talk to the
daemon in this case because QEMU guests can only ever by of type 'hvm'.

Dan.
