Ian Wienand 2978ff885b Revert Xenial to Python 2
There are issues with pip packages and a python3 only Xenial systems.
This is occuring after Ie609de51cc5fcde701296c9474e315981d9778a2.

We believe the issue is with VIRTUAL_ENV being set within the chroot
and messing up pip installs
(Icdb769541eee9793f261b4b8ec563be76ee13fe2) but a full solution is not
yet clear.

For now, set Xenial to ensure we use python2.  Install the package for
the ubuntu element (75-debian-minimal-baseinstall will install python2
for the minimal elements).

dib-python

Adds a symlink to /usr/local/bin/dib-python which points at either a python2 or python3 executable. This is useful for creating #! lines for scripts that are compatible with both python2 and python3.

This does not install a python if one does not exist, and instead fails.

This also exports a variable DIB_PYTHON_VERSION which will either be '2' or '3' depending on the python version which dib-python points to.
