Subject: getsockopt.2: SYNOPSIS: Use 'restrict' in prototypes

getsockopt.2: SYNOPSIS: Use 'restrict' in prototypes

POSIX specifies that the parameters of getsockopt()
shall be 'restrict'.  Glibc uses 'restrict' too.
Let's use it here too.

socket/sys/socket.h:208:
extern int getsockopt (int __fd, int __level, int __optname,
		       void *__restrict __optval,
		       socklen_t *__restrict __optlen) __THROW;
