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

glibc uses 'restrict' in getservent_r(), getservbyname_r(),
getservbyport_r().
Let's use it here too.

.../glibc$ grep_glibc_prototype getservent_r
resolv/netdb.h:306:
extern int getservent_r (struct servent *__restrict __result_buf,
			 char *__restrict __buf, size_t __buflen,
			 struct servent **__restrict __result);
.../glibc$ grep_glibc_prototype getservbyname_r
resolv/netdb.h:310:
extern int getservbyname_r (const char *__restrict __name,
			    const char *__restrict __proto,
			    struct servent *__restrict __result_buf,

			    struct servent **__restrict __result);
.../glibc$ grep_glibc_prototype getservbyport_r
resolv/netdb.h:316:
