Because we copy camera app into system app to have camera feature in lockscreen (system app). in `install-gaia.py` we copy localization files into gaia, so we willl get localization files when we copy camera app into system app.

but we no longer copy localization file into gaia, so we need correct path to get localization file for camera in system, that's what this workaround did, modify
```
LOCALE_BASEDIR/pl/apps/system/camera/camera.properties
```
to 
```
LOCALE_BASEDIR/pl/apps/camera/camera.properties
```
