build-unit-test-docker: use LLVM APT repos
The latest version of clang-18 from ubuntu's apt is 18.1.3,
but the latest stable release is 18.1.8. These two versions have
different output on some repositories when using clang-format. Switch
to using the apt.llvm.org packages so we get the latest stable versions.
The LLVM apt install tool needed a few additional packages to be
installed, so add those to the base apt-get.
