kselftests: timers: Add test for frequency step

This test checks the response of the system clock to frequency
steps made with adjtimex(). The frequency error and stability of
the CLOCK_MONOTONIC clock relative to the CLOCK_MONOTONIC_RAW clock
is measured in two intervals following the step. The test fails if
values from the second interval exceed specified limits.
