python distro package support

[geissonator]

Moving to python3 caused us to lose support for platform.linux_distribution(). It's recommended that we move to this new distro python package (https://pypi.org/project/distro/#files).

I don't see a recipe for this yet and was wondering if anyone else was working on one? If not, I could look into making one and putting up a PR.

@geissonator thanks for the report, is it possible for you to write a recipe and send, if not you can still use meta-python2 and get all python2 related packages.

ok, put a PR up at #213
