Switch base image away from Alpine

[GeckoEidechse]

Alpine with musl instead of glibc is known to cause issues with Wine. This repo alone already has a bunch of custom patches to deal with this.

Further we cannot even update the curl version used in Northstar (https://github.com/R2Northstar/NorthstarLauncher/pull/578) cause it doesn't play nice with the OS + Wine combo used in Docker image.

Switching the base to something like debian or the like should help alleviate this.

(I'm well aware that this basically requires rewriting the docker image from scratch)
