KVM: selftests: Use __stringify() instead of custom XSTR() macros

Browse Source 
Drop the custom defined XSTR() macros in KVM selftests and use
__stringify() instead. Include stringify.h in test_util.h to make it
available for all tests instead of including it in all the tests that
need it, as more tests will start using it.

No functional change intended.
