Move the pre-auto-gc hook away from run-command.h to and over to the
new hook.h library.

To do this introduce a simple run_hooks_oneshot() wrapper, we'll be
using it extensively for these simple cases of wanting to run a single
hook under a given name, and having it free the memory we allocate for
us.
