timer_test: do not use real time: deterministic and faster

Use osmo_gettimeofday_override* to decouple the timer test from real time. No
longer call osmo_select_main(), since select() actually waits for real time.

This reduces the timer_test to the osmo_timer_* logic and excludes the real
time and osmo_timers_nearest() accuracy testing with actual waiting involved.
This may be seen as a loss, but is more fit for a test suite.

The main point here is to get deterministic results in jenkins, so that we
don't have to retrigger jobs based on timing failures; added bonus is that the
test runs much faster now.
