[Libvir] Patch for pkg-config file cflags

[Daniel P. Berrange]

The libvirt.pc.in file has an empty field for the cflags variable, so
if you install libvirt into any prefix which is not in the compiler's
default include file search path the header files won't be found when
compiling applications. Attching a patch which corrects the pkg-config
file for libvirt

Regards,
Dan.
