LibIPC: Add IPC::take_over_accepted_client_from_system_server<Client>()

Browse source 
This is an encapsulation of the common work done by all of our
single-client IPC servers on startup:

    1. Create a Core::LocalSocket, taking over an accepted fd.
    2. Create an application-specific ClientConnection object,
       wrapping the socket.

It's not a huge change in terms of lines saved, but I do feel that it
improves expressiveness. :^)
