Capture conda build version

I'm not certain if/how possible this is, but it might be nice to capture the conda build version being used and the binary compatibility information.

conda-build version used is easy. It's encoded in a package's about.json, so you don't need to record it at build time.

Binary compatibility is a lot harder. It's different on every platform, and I think you'd need to start up some kind of database to match up symbols provided with symbols used. Conda-build 3's run_exports is a decent approximation, but not truly tracking binary compatibility directly.
