[libvirt] [PATCH] [configure] Fix libvirt dependency, and use $VAPIGEN

This is a rather trivial patch to raise the minimum libvirt dependency; at least 0.9.4 is required. In addition, it fixes the direct usage of `vapigen`, and uses the result of the AC_PATH_PROG(VAPIGEN ...) call earlier so that the binary to be used can be overridden as that macro was meant to allow.
