Update the XCP-ng Linux Detectionxcp

- All supported releases have an /etc/os-release file so nuke the legacy detection
- The platform ID in the os-release file is XCP-ng in 7 and xenserver in 8 (this is a bug IMO) so update the XCP match
- Downcase platform IDs. It seems like everyone makes these lowercase, but XCP-ng. There may be others and ohai platforms need to be lowercase
