Code review comment for ~paelzer/ubuntu/+source/ipxe:merge-ipxe-groovy-36a4c85-5

The discussion on the HTTPS/config enabling/disabling clarified that we don't need to change the config=qemu behavior on legacy roms.

I adapted the changelog and the former

    - d/rules: only enable https on non EFI roms and CONFIG=qemu only on EFI
      roms. This lets EFI handle https itself and avoids breakage in TPL
      manipulations (LP: #1882671)

I force pushed the branch to reflect this
