    libc: tests: hook CPUSET(9) test up to the build
    
    Add shims to map NetBSD's API to CPUSET(9). Obviously the invalid input
    parts of these tests are relatively useless since we're just testing the
    shims that aren't used elsewhere, there's still some amount of value in
    the parts testing valid inputs.
