getsockname.2: Use restrict in prototypes

POSIX specifies that the 2nd and 3rd parameters to getsockname()
shall be 'restrict'.  Glibc uses 'restrict' too.
Let's use it here too.

......

.../glibc$ grep_syscall_wrapper getsockname
socket/sys/socket.h:116:
extern int getsockname (int __fd, __SOCKADDR_ARG __addr,
			socklen_t *__restrict __len) __THROW;
.../glibc$ grep -rn '# *define __SOCKADDR_ARG'
socket/sys/socket.h:58:
 # define __SOCKADDR_ARG		struct sockaddr *__restrict
.../glibc$

function grep_syscall_wrapper()
{
	if ! [ -v 1 ]; then
		>&2 echo "Usage: ${FUNCNAME[0]} <syscall>";
		return ${EX_USAGE};
	fi

	find * -type f \
	|grep '\.h$' \
	|sort -V \
	|xargs pcregrep -Mn \
	  "(?s)^[^\s#][\w\s]+\s+\**${1}\s*\([\w\s()[\]*,]*?(...)?\)[\w\s()]*;" \
	|sed -E 's/^[^:]+:[0-9]+:/&\n/';
}
