Allow control of 2nd arg to segsetjmp() via -DSCOPE_SAVES_SIGNAL_MASK.
(So Alan and Ilya can try setting via hints.)
Verified Linux "works" with it true and fails to re-enable SIGINT if false.
Restoring sigmask in Perl_sighandler() if handler dies is not equivalent;
doing the save everywhere seems to restart read() correctly, but just
doing it once "round" the handler does not.
