Move //mojo/services/network/public/interfaces to //mojo/services/network/interfaces.

Also, update this directory to exactly match the one in monet at
0a814ed5512598e595c0ae7975a09d90a7a54e90 (aside from changes required by
the move, this only updates the BUILD.gn in that directory in a minor
way).
