Ian Wienand 8662297517 Deprecate dib-python; remove from in-tree elements
We are at the point that all distributions we are building have Python
3, so any tools running in the chroot can assume Python 3 exists.
This makes dib-python redundant; mark it as deprecated and start to
remove it from elements where it is no longer required.
