tests: Tweak vircapstest_LDADD

We optionally include QEMU and LXC support in this test and
depending on which is enabled (if either is enabled at all) we
need to link in different objects.

Right now we implicitly depend on the fact that qemu_LDADDS is
empty when QEMU is not enabled to get the correct set of objects,
but it's better to be explicit about it.
