[PATCH 21/23] rexec.3: SYNOPSIS: Use 'restrict' in prototypes

[Alejandro Colomar <alx.manpages@gmail.com>]

glibc uses 'restrict' in rexec(), rexec_af().
Let's use it here too.

.../glibc$ grep_glibc_prototype rexec
resolv/netdb.h:477:
extern int rexec (char **__restrict __ahost, int __rport,
		  const char *__restrict __name,
		  const char *__restrict __pass,
		  const char *__restrict __cmd, int *__restrict __fd2p);
.../glibc$ grep_glibc_prototype rexec_af
resolv/netdb.h:489:
extern int rexec_af (char **__restrict __ahost, int __rport,
		     const char *__restrict __name,
		     const char *__restrict __pass,
		     const char *__restrict __cmd, int *__restrict __fd2p,
		     sa_family_t __af);
.../glibc$
