[OE-core] [PATCH] recipetool: support python3 instead of python2

[Maciej Pijanowski]

Add support for generating python3 recipes using the recipetool / devtool.
Drop python2 support at the same time.

Tested with:

devtool add --also-native python3-python-magic \
https://files.pythonhosted.org/packages/84/30/\
  80932401906eaf787f2e9bd86dc458f1d2e75b064b4c187341f29516945c/\
  python-magic-0.4.15.tar.gz

No python2 dependencies were pulled in

Fixes Bug 13264
