On Solaris 11.4, I see this compilation error:
../../gltests/test-sys_socket-h.c: In function 'main':
../../gltests/test-sys_socket-h.c:169:10: error: 'MSG_CMSG_CLOFORK' undeclared
(first use in this function); did you mean 'SOCK_CLOFORK'?
case MSG_CMSG_CLOFORK:
^~~~~~~~~~~~~~~~
SOCK_CLOFORK
../../gltests/test-sys_socket-h.c:169:10: note: each undeclared identifier is
reported only once for each function it appears in
gmake[4]: *** [Makefile:27884: test-sys_socket-h.o] Error 1
This patch fixes it.

sys_socket-h tests: Avoid compilation error on Solaris 11.4.
* doc/posix-headers/sys_socket.texi: Update.
* tests/test-sys_socket-h.c (main): Don't assume that all platforms that
have SOCK_CLOFORK also have MSG_CMSG_CLOFORK.
