runtime: when disabling SIGPROF handler, ignore SIGPROF

If the runtime disables the SIGPROF handler, because this is Go code
that is linked into a non-Go program, then don't go back to the
default handling of SIGPROF; just start ignoring SIGPROF.
Otherwise the program can get killed by a stray SIGPROF that is
delivered, presumably to a different thread, after profiling is disabled.

Fixes #19320
