If a signal lands on a non-Go thread, and Go code doesn't want to
handle it, currently we re-raise the signal in the signal handler
after uninstalling our handler, so the C code can handle it.
But if there is no C signal handler and the signal is ignored,
there is no need to re-raise the signal. Just ignore it. This
avoids uninstalling and reinstalling our handler, which, for some
reason, changes errno when TSAN is used. And TSAN does not like
errno being changed in the signal handler.
Not really sure if this is the bset of complete fix, but it does
fix the immediate problem, and it seems a reasonable thing to do
by itself.
Test case is CL 581722.
Fixes#66427.

Unfortunately, LLVM TSAN decided to remove OpenBSD support, which
means that the syso files cannot currently be regenerated (see #52090).
The race_openbsd.syso contains a reference to the syscall symbol,
which has been removed from OpenBSD's libc in 7.5. As such, this
means that the race detector no longer works on openbsd/amd64 (at
least until LLVM TSAN support is reinstated for OpenBSD).
