Cleanup unused images (#349)

With @simondeziel we have checked the metrics for images, and this PR
drops builds for unused images, especially focusing on distributions
that are very *heavy* to build, such as Funtoo, and openEuler.

This removes builds for:
- Devuano (arm64 only)
- Gentoo (arm64 only)
- Funtoo (arm64 only)
- openEuler 22.03 (all)
- openEuler 24.03 (arm64 only)
- Oracle 8 (arm64 only)
- ALT p10 (all)
