A test to check that all supported clocks work on host and inside a new time namespace. Use both ways to get time: through VDSO and by entering the kernel with implicit syscall. Introduce a new timens directory in selftests framework for the next timens tests.

How long does this test run for? Does this test need to be run as root? If yes, please add a root check and skip the test. What does the test output looks like for skip and pass/fail cases? thanks, -- Shuah
