4b881cf8 - [test] lit.cfg: Introduce config.target_library_path_var for the correct spelling of DYLD_LIBRARY_PATH

[test] lit.cfg: Introduce config.target_library_path_var for the correct spelling of DYLD_LIBRARY_PATH Instead of setting a random subset of `DYLD_LIBRARY_PATH`, `LD_LIBRARY_PATH`, `SIMCTL_CHILD_DYLD_LIBRARY_PATH`, `REMOTE_RUN_CHILD_DYLD_LIBRARY_PATH`, and `REMOTE_RUN_CHILD_LD_LIBRARY_PATH` in each `target_run` configuration, simply arrange for the single correct variable name to be in `config.target_library_path_var`, and set it only once. This should remove irrelevant environment variables from test logs, making them a little less confusing.
