[libvirt] [PATCH] qemuxml2argvtest: uncoditionally mock NUMA routines

Currently, qemuxml2argvmock.c only mocks virNumaNodeIsAvailable(), and
only if libvirt was built with NUMA support. This causes some test
failures where NUMA is involved.

For example, memory-hotplug-dimm fails because it goes all they way down
to qemuBuildMemoryBackendStr() that calls virNumaNodesetIsAvailable()
for a user specified nodeset and fails, hence the test (unexpectedly)
fails.

To make qemuxml2argtest successfully run on non-NUMA platforms, do the
following:

 - mock virNumaNodeIsAvailable() unconditionally
 - add a mock for virNumaNodesetIsAvailable()
