test_siginterrupt_off unnecessarily takes 30 minutes in refleak test

[colesbury]

Bug report

The test_siginterrupt_off test in test_signal expects a timeout and uses support.SHORT_TIMEOUT.

In at least some of the refleak test runners:

• we bump the overall timeout to 200 minutes:
• which adjusts support.SHORT_TIMEOUT to five minutes
• and the test case is run six times

So the test always takes a minimum of 30 minutes.
