error in prepare_instrumentation.sh related to strip_split_rendering.sh

While running the script locally, I encountered an error, and looking at a recent pipeline it seems the same is present there:

prepare_instrumentation.sh: line 90: strip_split_rendering.sh: command not found

The two things I had to do to fix this locally were to prepend a ./ and also mark the script as executable (this error was present for be both on macOS and Linux).
