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

glibc uses 'restrict' in getpwent_r(), fgetpwent_r().
Let's use it here too.

.../glibc$ grep_glibc_prototype getpwent_r
pwd/pwd.h:139:
extern int getpwent_r (struct passwd *__restrict __resultbuf,
		       char *__restrict __buffer, size_t __buflen,
		       struct passwd **__restrict __result)
		       __nonnull ((1, 2, 4));
.../glibc$ grep_glibc_prototype fgetpwent_r
pwd/pwd.h:166:
extern int fgetpwent_r (FILE *__restrict __stream,
			struct passwd *__restrict __resultbuf,
			char *__restrict __buffer, size_t __buflen,
			struct passwd **__restrict __result)
			__nonnull ((1, 2, 3, 5));
