centos8: don't download .repo file

Generate the .repo file on the fly instead of downloading it from the
OBS repository. Ensure the gpgkey gets downloaded via HTTPS. I'm about
to use centos8-obs-latest with an alternative repository, which does not
have the .repo file. Adjust other containers for consistency.
