run-command: introduce function to prepare auto-maintenance process 

The `run_auto_maintenance()` function is responsible for spawning a new
`git maintenance run --auto` process. To do so, it sets up the `sturct
child_process` and then runs it by executing `run_command()` directly.
This is rather inflexible in case callers want to modify the child
process somewhat, e.g. to redirect stderr or stdout.

Introduce a new `prepare_auto_maintenance()` function to plug this gap.
