Hi Emily

As part of the adoption of config-based hooks, teach run_commit_hook()
to call hook.h instead of run-command.h. This covers 'pre-commit',
'commit-msg', and 'prepare-commit-msg'. Additionally, ask the hook
library - not run-command - whether any hooks will be run, as it's
possible hooks may exist in the config but not the hookdir.

Seeing this makes me wonder if it would be better for run_hooks() to
take a string for the name rather than an strbuf, I suspect that
virtually all callers have a fixed hook name.
