sanitytest.py: Do not rely on system libvirt
sanitytest.py: Do not rely on system libvirt

When running sanitytest.py we should not rely on libvirt library
installed on the system. And since we generate a nice wrapper called
"run" that sets both PYTHON_PATH and LD_LIBRARY_PATH, we should just use
it rather than trying to duplicate it in the Makefile.
