Subject: [PATCH] sigwait.3: SYNOPSIS: Use 'restrict' in prototypes

Both POSIX and glibc use 'restrict' in sigwait().
Let's use it here too.

.../glibc$ grep_glibc_prototype sigwait
signal/signal.h:255:
extern int sigwait (const sigset_t *__restrict __set, int *__restrict __sig)
     __nonnull ((1, 2));
.../glibc$
