Avoid initial 3ms pause on world stop/start with GC_retry_signals (Linux)
(a cherry-pick of commit 09d56ab44 from Unity-Technologies/bdwgc)
The existing GC_retry_signals case would almost always introduce a 3ms
pause when stopping and starting the world. Instead only fallback to
that retry case if the threads haven't responded after a timeout.

resend_lost_signals() and suspend_restart_barrier() (if
GC_retry_signals).
