Could you break them to 2 separate patches, please?

I'm not sure I follow what are you trying to achieve by changing the src_root.

Changing src_root would not give you ../llvm/runtimes, it simply changes where the source code gets checked out to. Like <buildbot-worker-directory>/<builder>/runtimes/llvm-project/<the rest of the monorepo tree>.
