[sancov] Run more sancov tests on non-x86-Linux machines
Add the $arch-registered-target features that clang uses to disable
tests that require a registered backend, so that we can run the sancov
tests on Windows. LLVM's lit suite did not appear to have a per-test way
to do this, and I would rather not split up the sancov tests into
architecture directories.
