The following 4 tests in timers can take longer than the default 45
seconds that added in commit 852c8cbf34d3 ("selftests/kselftest/runner.sh:
Add 45 second timeout per test") to run:
  * nsleep-lat - 2m7.350s
  * set-timer-lat - 2m0.66s
  * inconsistency-check - 1m45.074s
  * raw_skew - 2m0.013s

Thus they will be marked as failed with the current 45s setting:
  not ok 3 selftests: timers: nsleep-lat # TIMEOUT
  not ok 4 selftests: timers: set-timer-lat # TIMEOUT
  not ok 6 selftests: timers: inconsistency-check # TIMEOUT
  not ok 7 selftests: timers: raw_skew # TIMEOUT

Disable the timeout setting for timers can make these tests finish
properly:
  ok 3 selftests: timers: nsleep-lat
  ok 4 selftests: timers: set-timer-lat
  ok 6 selftests: timers: inconsistency-check
  ok 7 selftests: timers: raw_skew

I was hoping to get Ack from timers test maintainers.

Will pull this in for my fixes update.

Apologies for missing this before.  I've not tested with this, but it
sounds sane to me. A number of the timekeeping tests do take a while
to run.
