Subject: [PATCH] Add Alma 9 build container (#250)

This is the `[registry.cern.ch/]alisw/slc9-builder` container.

I've cut down the number of installed packages compared to slc8-builder:

* Build requirements are tracked in alice-o2-full-deps, so reuse that package.
  This way we also have the same setup in the container and for users' local
  builds, easing debugging.
* Java is not required since we always use the one from `alidist/jdk.sh`, and
  JDK 8 is too old to be used for JAliEn anyway.
* The extra development tools and X11 libraries were a holdover from the
  alidock days, and are not used any more.
* I also removed some RPM repo-specific tools like `fpm` and `createrepo`,
  since we use the slc8 container for those at the moment, and in future I'd
  like to move that to a separate `alisw/publisher` container, to save space
  in this one.

I also based the container on the CERN Alma 9 base image, to have the CERN yum
repos already installed in addition to the standard ones.
