add back NSIG, removed from powerpc in last commit, but for all archs
unlike the previous definition, NSIG/_NSIG is supposed to be one more than the highest signal number. adding this will allow simplifying libc-internal code that makes signal-related syscalls, which can be done as a later step. some apps might use it too; while this usage is questionable, it's at least not insane.
