getnameinfo.3: SYNOPSIS: Use 'restrict' in prototypes 

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

I consciously did an exception with respect to the right margin
of the rendered page.  Instead of having the right margin at 78
as usual (per Branden's recommendation), I let it use col 79
this time, to avoid breaking the prototype in an ugly way.

.../glibc$ grep_glibc_prototype getnameinfo
resolv/netdb.h:675:
extern int getnameinfo (const struct sockaddr *__restrict __sa,
			socklen_t __salen, char *__restrict __host,
			socklen_t __hostlen, char *__restrict __serv,
			socklen_t __servlen, int __flags);
.../glibc$
