runtime: minor simplifications to signal code
Change setsig, setsigstack, getsig, raise, raiseproc to take uint32 for
signal number parameter, as that is the type mostly used for signal
numbers. Same for dieFromSignal, sigInstallGoHandler, raisebadsignal.
Remove setsig restart parameter, as it is always either true or
irrelevant.
Don't check the handler in setsigstack, as the only caller does that
anyhow.
Don't bother to convert the handler from sigtramp to sighandler in
getsig, as it will never be called when the handler is sigtramp or
sighandler.
Don't check the return value from rt_sigaction in the GNU/Linux version
of setsigstack; no other setsigstack checks it, and it never fails.
