remove some packages from the package table

* go-libp2p-coral-dht is currently being written and shouldn't go in this list
  until it's reasonable usable (unless I'm missing the point of this list).
* go-libp2p-ping is an unmaintained extraction of go-libp2p/p2p/ping
* go-libp2p-pubsub is slated to be removed.
* go-libpp2-dummy-conn was implemented to test go-libp2p-pnet. (1)
  go-libp2p-pnet can now be tested with normal `io.ReadWriteCloser`s so it
  doesn't need this package and (2) I didn't bother updating this package when I
  did the libp2p transport refactor.
