setuptools: use entry_points.

Makes it easier to package this as an installable application.

This looks OK to me, but Kim should be the one to accept/reject.

This needs some work. I wasn't able to get it to work locally (but that could be an issue on my part). But even if it does work, it changes the invocation from python get_trust_anchor.py to get-trust-anchor and therefore the documentation needs to be updated to reflect that. Also underscores in module names isn't idiomatic.

I more or less followed the steps described in [1]. By underscores, do you mean the underscores from the `__main__` part? If you happen to use Guix, there's a submission [1] to add this as a package and it includes this patch.
