gnomeExtensions: add patch framework

It's like Haskell's overlay system, but way more primitive. We simply pre-define some
package overrides that are required for an automatically packaged extension to work.
Ideally, all (or almost all) currently manually pacakged extensions will work this way.

Since these are mostly just a few lines each, there is no need to split this up into a
lot of small files.
