Fixed an oversight if the default CXPatcher bottles directory could not be found

If the executable does not run on the first attempt:

1. Execute chmod 0755 ./MetalHUDEnabler in a terminal
2. Right click on MetalHUDEnabler wherever you saved it in Finder and click "Open"
3. Try executing it again in a terminal afterwards

Full Changelog: 2.5...2.5.1
