Add missing MSG_CMSG_CLOEXEC
Unpatched uClibc toolchains, even using the latest 0.9.33.2, do not
have the MSG_CMSG_CLOEXEC definition. Even though the Buildroot
internal toolchain backend has a uClibc patch to provide it, it
doesn't apply to external toolchains. This patch provides the
definition of MSG_CMSG_CLOEXEC.
