Subject: [PATCH] Block EL9 minor version upgrades

Since kABI migrations across minor versions is a thing of the past going
forward, we now:
- Detect if we're on EL9
- If so, add a requirement on the various flavors of release package to
  that specific major.minor version

This appropriately does not allow upgrades across minor versions.
