Bug #13096353 62712: RPM-BASED INSTALL OF THE TEST SUITE IS USELESS FOR NON-ROOT USERS
Simplified fix avoiding changes to mysys: Use the MY_HOLD_ORIGINAL_MODES flag when calling my_copy(), this also stops it from attempting to chown() the file. Yes this behavior is a bit confusing.... The only case this might change the behavior is if the destination file exists, but since we also use MY_DONT_OVERWRITE_FILE, it would fail in those cases anyway.
