runtime: allow signal.Ignore of user-generated throwing signals
Today, signal.Ignore(syscall.SIGTRAP) does nothing
while signal.Notify(make(chan os.Signal), syscall.SIGTRAP)
correctly discards user-generated SIGTRAPs.
The same applies to any signal that we throw on.
Make signal.Ignore work for these signals.
Fixes #12906.
