Fix llvm version conflict after upgrade to RHEL9.6

Browse Source 
Add --allowerasing, which will downgrades some packets in order to
satisfy LLVM dependencies.

When building the docker image for clang, CI fails with

    Error:

      - conflicting requests
      - problem with installed package mesa-libGL-devel-24.2.8-2.el9_6.x86_64
    (try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

So when trying to install llvm-toolset from docker/Dockerfile.clang.rhel9,
we have a conflict because this installs 18.1 from ubi-9-appstream-rpms,
but various mesa packets have llvm 19.1.

1. I don't understand why we have mesa installed (no graphics system?)
2. --allowerasing downgrades the relevent mesa package(s)

Alternatively, we would need to select 19.1 when installing
llvm-toolset, but I don't know how to do that.
