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

POSIX does NOT specify these functions to use 'restrict'.
However, glibc uses 'restrict' in getpwnam_r(), getpwuid_r().
Let's use it here too.

.../glibc$ grep_glibc_prototype getpwnam_r
pwd/pwd.h:151:
extern int getpwnam_r (const char *__restrict __name,
		       struct passwd *__restrict __resultbuf,
		       char *__restrict __buffer, size_t __buflen,
		       struct passwd **__restrict __result)
		       __nonnull ((1, 2, 3, 5));
.../glibc$ grep_glibc_prototype getpwuid_r
pwd/pwd.h:145:
extern int getpwuid_r (__uid_t __uid,
		       struct passwd *__restrict __resultbuf,
		       char *__restrict __buffer, size_t __buflen,
		       struct passwd **__restrict __result)
		       __nonnull ((2, 3, 5));
