  [libc] Prevent changing ownership of the port once opened

The Port type has stipuations that the same exact mask used to open it
needs to close it. This can currently be violated by calling its move
constructor to put it somewhere else. We still need the move constructor
to handle the open and closing functions. So, we simply make these
constructors private and only allow a few classes to have move
priviledges on it.
