    cli: reset db directory mtime upon directory removal

we don't have an interface to delete directory documents, and they're
left behind. Add the interface.

XXX: Should this also remove the files under it, or assume that's been
done by the caller? Should this incorporate some or all of the
functionality of _remove_directory() in notmuch-new.c?
