[3.13] gh-120039: Reduce expected timeout in test_siginterrupt_off (GH-120047) (#120060)

Browse source 
The process is expected to time out. In the refleak builds,
`support.SHORT_TIMEOUT` is often five minutes and we run the tests six
times, so test_signal was taking >30 minutes.
(cherry picked from commit d419d468ff)
