Commit a745f7af3cbd ("selftests/harness: Add 30 second timeout per test") adds an hardcoded 30s timeout to all tests. Unfortunately, rtctest has two tests taking up to 60s. Allow for individual tests to define their own timeout.

Ah yes. Very nice; thanks!

uie_read is a commonly failing test that will block forever on buggy rtc drivers. Shorten its timeout so it fails earlier. Also increase the timeout for the two alarm test on a minute boundary.
