At the old location, it would always output the project, including "flang-rt". I could have added an if-condition to not print flang-rt, or filter it out afterwards in like in `exclude-linux`/`exclude-windows` but that doesn't seem its purpose, or just let it add it to "LLVM_ENABLE_PROJECTS" even though it it ignored there (like "llvm"). I found the best solution is to change the function to let each case decide whether to prints itself, which would also e.g. allow to not print "llvm" at some point. 

I avoided modifying https://github.com/llvm/llvm-project/blob/main/.ci/generate-buildkite-pipeline-premerge itself, there are copies of that code, like in https://github.com/llvm/llvm-project/blob/main/.github/workflows/premerge.yaml
