* [DayZ] Image Cleanup
- Removed `numactl` dependency as it seems SteamCMD updated and resolved its crashing issues on Linux when logging in with a real account.
- Added clearing of SteamCMD appworkshop cache before mod downloads to avoid potential failures (at least until I implement a better method using symlinks for mod folders).
- General cleanup of text and labels.
* Fix missing `WORKSHOP_DIR` global var
