Revert "Dont install python-pip for py3k"

Browse Source 
This reverts commit ab89c7d69c.

This commit checked for DIB_PYTHON_VERSION and only installed the v3
packages.  This is unfortunately backwards-incompatible, as consumers
such as the openstack gate are relying on this package installing pip
& virtualenv packages for python2 AND python3.

This was sort-of expressed in the docs, where it discusses what the
resulting setup of the system will be, but I've added a note to make
it clearer.

If we want to change this, I think we'll need either a new element, or
a non-defaulting flag.
