I assume you've already gone for the more obvious and seen if you can
upgrade keras to 2.3.1?

Indeed :)

Starting from Keras 2.2.5, the other backends are unconditionally
required by the tests, so it won't do :(

Not sure what to do about it. In all cases, it's a a lot of work, so I
figured we'd rather get 2.2.4 to build at least.
