WIP: Dynamic Kernel Module Support

Not yet completly tested, currently stuck on kernel sources on the pinephone. I dont think this is the best solution for automatic upgrading after a kernel upgrade.

• DKMS runs
• Getting a module packaged (sortof, has to be optimized, modules have versions too)
• Exporting kernel headers (im slowly confused)
• DKMS compiles the module on the device
• module works

The dkms aport can perhaps be upstreamed to alpine?

See this comment

Not really. Several Alpine devs have already expressed their dislike of DKMS in the past, I severely doubt they want this.

P.S.: FYI, I'm waiting a bit until I'm certain I have the time to maintain it. I'm not quite sure as the pandemic is still around.
