ualarm(2) is obsolete. Move IntervalTimer into a test util, where it can be used by flock tests. These tests were flaky with TSAN, probably because it slowed the tests down enough that the alarm was expiring before flock() was called. Use an interval timer so that even if we miss the first alarm (or more), flock() is still guaranteed to be interrupted. PiperOrigin-RevId: 337578751
