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

POSIX does NOT specify scandir() to use 'restrict'.
However, glibc uses 'restrict'.
Users might be surprised by this!  Let's use it here too!

.../glibc$ grep_glibc_prototype scandir
dirent/dirent.h:255:
extern int scandir (const char *__restrict __dir,
		    struct dirent ***__restrict __namelist,
		    int (*__selector) (const struct dirent *),
		    int (*__cmp) (const struct dirent **,
				  const struct dirent **))
     __nonnull ((1, 2));
.../glibc$
