AlmaLinux 8 — cloud-init

Mirror: https://mirror.scalewithus.com

For AlmaLinux 9 see almalinux.md; for 10 see almalinux-10.md.

Alma 8 ships split repo files (almalinux-*.repo). Patch those — do not create a combined almalinux.repo (duplicate IDs). On EL8 the optional rebuild tree is PowerTools (not CRB).
