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

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

glibc uses 'restrict' in scandirat().
Let's use it here too.

.../glibc$ grep_glibc_prototype scandirat
dirent/dirent.h:293:
extern int scandirat (int __dfd, const char *__restrict __dir,
		      struct dirent ***__restrict __namelist,
		      int (*__selector) (const struct dirent *),
		      int (*__cmp) (const struct dirent **,
				    const struct dirent **))
     __nonnull ((2, 3));
.../glibc$
