Actually I don't think that it's going to work for python3, since
python(2.7) and python3 are separate recipes that does not provide the same
package (python). They provide two different packages: python and python3,
respectively.
And I believe that PREFERRED_VERSION just have effects on local.conf,
machine.conf and distro.conf, not on image recipes.

Maybe using update-alternatives class can help me to achieve this:
