linux: simplify adding new extensions
Curently, all three linux extensions follow the same layout:
- test if the extension is enabled
- add itself to linux' patch-dependencies
- declare a macro, added as the pre-patch hook
Except for the macro, all can be commonalised.
Add a simple infrastructure for that:
- extensions declare themselves in the list of extensions
- extensions define their macro
- the infra adds them to the patch-dependencies and pre-patch
hooks as appropriate
