Jeff King 72da9832c2 run-command: mark unused parameters in start_bg_wait callbacks ...

The start_bg_command() function takes a callback to tell when the
background-ed process is "ready". The callback receives the
child_process struct as well as an extra void pointer. But curiously,
neither of the two users of this interface look at either parameter!

This makes some sense. The only non-test user of the API is fsmonitor,
which uses fsmonitor_ipc__get_state() to connect to a single global
fsmonitor daemon (i.e., the one we just started!).

So we could just drop these parameters entirely. But it seems like a
pretty reasonable interface for the "wait" callback to have access to
the details of the spawned process, and to have room for passing extra
data through a void pointer. So let's leave these in place but mark the
unused ones so that -Wunused-parameter does not complain.
