torify.in can turn back into torify
Once we had torify.in get preprocessed so that we could have a LOCALSTATEDIR reference in it or something. But we no longer need to set up an explicit tsocks configuration, now that we've removed torify's support for tsocks ... so we no longer need to preprocess torify.in into torify.
We should therefore:
- Rename torify.in to torify
- Remove torify from .gitignore
- Make torify, not torify.in get distributed
- Remove torify from the list of things that made by the aclocal substitution
