[PATCH] socketlib, sockets, sys_socket: Use AC_REQUIRE to pacify autoconf.

[Paul Eggert]

Without this change, in bleeding-edge fileutils Autoconf complains
that gl_SOCKETLIB etc. are AC_REQUIREd after being invoked.
* modules/socketlib (configure.ac): AC_REQUIRE gl_SOCKETLIB.
* modules/sockets (configure.ac): AC_REQUIRE gl_SOCKETS.
* modules/sys_socket (configure.ac): AC_REQUIRE gl_HEADER_SYS_SOCKET.
