socket: Fix tst-cmsghdr-skeleton.c use of cmsg_len
cmsg_len is supposed to be socklen_t according to standards, but it was made size_t on Linux, see BZ 16919. For ports that have it socklen_t, SIZE_MAX is too large. We can however explicitly cast it to the type of cmsg_len so it will fit according to that type.
