Revert of Add setup.py to infra_libs (patchset #1 id:1 of https://codereview.chromium.org/2129103004/ )

Reason for revert:
I think I rushed it - setup.py doesn't really work without a deeper module structure. It needs to be next to infra_libs, not inside it.

Original issue's description:
> Add setup.py to infra_libs

> This is to allow creating a correct wheel out of it, for use with glyco
> and in the future, possibly pip / PyPI.
