That's a bug in virportallocatortest.c that was introduced in
0ee90812. The init_syms() fnuction should *not* be calling
VIR_FORCE_CLOSE - it must use close(), because this is the
mock-override and so should not be using libvirt.so symbols.

Nope as above, we should not be linking libvirt.la to the mock lib,
because the mock lib is supposed to be replacing libvirt.la symbols
