Revert "Merge pull request #4693 from flosse/hplip-update"

This reverts commit 1b064645ed10a2bee70faec6896d4d33e2a86300, reversing
changes made to 14cef95e84e44a830b7317c095c7ffd6b9796fef.

As discussed in the comments to the aforementioned pull request, while
the new version supports many new printer models, many components of the
driver are broken because of some corner cases in the Python wrapper. In
particular, the loader for the binary binary driver needed by many
middle- and high-end printers is broken, negating most of the value in
updating!
