[PATCH] qemu: extract function qemuDomainDefIsUEFI()

[Jonathon Jongsma <jjongsma@xxxxxxxxxx>]

Rather than repeating the conditions in a couple places, extract it into
a separate function for detecting whether a domain definition uses UEFI.

As requested by Andrea, I've extracted this little bit of refactoring from my
bochs display patch and am sending it separately.
