cherry: don't set ignored rev_info options

Ever since cherry was built-in in e827633 (Built-in cherry,
2006-10-24), it has set a bunch of options on the the rev_info that
are only used while outputting a patch. But since the built-in cherry
command never needs to output any patch (it uses add_commit_patch_id
and has_commit_patch_id instead), these options are just distractions,
so remove them.
