Mindustry: Fix v102 scan errors
Mindustry build v102 fails: https://f-droid.org/wiki/page/io.anuke.mindustry/lastbuild_102 https://github.com/Anuken/Mindustry/issues/1308
the reasons are:
- an accidentally committed DS_store file recognized as binary
- DexClassLoader is found, which is used to load plugins
This patch fixed both through scan-ignore/delete.
