selftests/timers: Add clock skew estimation test from timetest suite
This adds my clock skew estimation test from the timetest suite.
It measures the drift between CLOCK_MONOTONIC and CLOCK_MONOTONIC_RAW
and compares it with the current frequency value from adjtimex.
It sometimes can trigger false failures when ntpd isn't in a
steady state, but its a useful too when doing adjtimex testing.
