bpf: git mv netd bpf/netd (plus update visibility for new path)

Another step towards moving all bpf related stuff into a common directory.

In practice netd_updatable is only actually used for bpf...

The upcoming netbpfload UML test should be checking netd_updatable's
initialization succeeds (useful since that opens a bunch of maps
fetches some programs, and attaches them to a bunch of cgroup hooks).
