extreload: Send extension IDs to extension

Send hard-coded extension IDs to the companion extension to tell it to
reload them. Start an event loop to keep the native host running
indefinitely.

We'll then be able to send extension IDs from a command line client to
the native host over a Unix domain socket IPC.
