Andrea Bolognani 4ceac4bf29 tests: Rename VIRT_TEST_* macros to VIR_TEST_*
We use the "vir" prefix pretty consistently in our
APIs, both external and internal, which made these
macros stood out.

/* The tests below make sure that the memory locking limit is being

* performed both on x86_64/pc and ppc64/pseries in order to account
* for some architecture-specific details.
*
* kvm: simple KMV guest
* tcg: simple TCG guest
*
* hardlimit: guest where <memtune><hard_limit> has been configured
* locked: guest where <memoryBacking><locked> has been enabled
* hostdev: guest that has some hostdev assigned
*
* The remaining tests cover different combinations of the above to
* ensure settings are prioritized as expected.
