vircapstest: fix build without LXC, QEMU or XEN

When building without lxc support enabled, build fails with:

CLD     vircapstest
vircapstest.o: In function `test_virCapsDomainDataLookupLXC':
vircapstest.c:(.text+0x9ef): undefined reference to `testLXCCapsInit'

Fix that by hiding LXC tests under appropriate #ifdef. Same applies
for QEMU and XEN.
