eBPF turn-off-ening

Description

• Make slim and full collector images the same.

  • x86 and s390x “full” images will not contain any drivers
  • Power slim and full images will both contain drivers (the current Power full image is only 10Mb larger than its slim equivalent)

• Keep legacy driver builds on master, but separate them from the main CI workflow

  • This will maintain observability while still removing complexity
  • no kernel packer changes required in this case, though we could reduce the crawl frequency
