Adds test for the diff util module.
Fixes an issue where
find_working_diff_command()!
adds spaces to the result, potentially making it unavailable to other commands. E.g.os.find_abs_path_of_executable
would not find the result of the function.Might even be required to make the changes in #21243 robust.
