This encapsulates what our multi-client IPC servers typically do on
startup:
1. Create a Core::LocalServer
2. Take over a listening socket file descriptor from SystemServer
3. Set up an accept handler for incoming connections
IPC::MultiServer does all this for you! All you have to do is provide
the relevant client connection type as a template argument.
