lib: new restore_wallclock field to restore realtime clock
Some tests that change the system-wide clock need to have a way to
restore the correct time after their execution.
This commit introduces a new field to tst_test struct called
"restore_wallclock": it makes the test to save current realtime clock
during setup phase, and, later, during cleanup, restore it to the
appropriate time using a monotonic raw clock difference.
