freebsd: move net/if_mib.h contents to submodule

There is a conflict of NETLINK_GENERIC definitions between net/if_mib.h and netlink/netlink.h. netlink.h is already exported in the crate root for Linux (and those definitions are already used by at least crates neli and netlink-packet-route), and if_mib is not much used yet, so this moves if_mib contents into its own namespace to leave place for netlink support on FreeBSD (#3194). Module definition moved to the end of file to avoid cryptic style.rs error "constant found after module when it belongs before". ctest as of 0.22 cannot be told a given header's symbols live in a submodule, so let the tests ignore all of them.
