ANDROID: cki_coverage: add timers testsuite

We're currently building and running the timers.* testcases, but
cki_coverage didn't inspect these tests.  After adding this testsuite to
the list of available and stable tests, we're now correctly reflecting
coverage for these syscalls:

- clock_gettime
- clock_settime
- timer_create
- timer_delete
- timer_settime
