Our struct child_process already has its own argv_array.
Let's use that to avoid having to format options into
separate buffers.
Note that we'll need to declare the child process outside of
the run_service_command() helper to do this. But that opens
up a further simplification, which is that the helper can
append to our argument list, saving each caller from
specifying "." manually.

Of all the patches in this series, this is the one where I was most
undecided on whether the result was more readable or not.
My ulterior motive, of course, was to get rid of the unchecked
snprintf() into timebuf. But it could also just become an xsnprintf()
with no further changes.
