This commit is just a copy of the patch that Dmitry Rozhkov submitted to openembedded-core, but it was rejected there [1]. If only python3 is installed on an image nothing provides /usr/bin/python even though many scripts compatible with both python2 and python3 just state `#!/usr/bin/env python` in their shebang line. Make python and python3 recipes provide alternatives for /usr/bin/python and /usr/bin/python-config. By default python2 has higher priority over python3. In meta-ros, we need this behaviour for ROS_USE_PYTHON3 = "yes" because ROS packages are always written to be python2 and python3 compatible.
