Exempt location packages from location indicators

* Otherwise it gets pretty spammy

config_locationProviderPackageNames:
* Pretty obvious, location providers, e.g. microG

config_locationExtraPackageNames:
* microG UnifiedNlp plugins
* https://cs.android.com/android/_/android/platform/frameworks/base/+/ffb94e69c3fc308d6d4164e2309f74442282fc84
* This grants location permissions, however we're excluding these apps from
  location indicators - they already have location permissions!
* https://cs.android.com/search?q=config_locationExtraPackageNames&sq=
* It isn't used for much else, so it's fine to re-use it for this

Test:
1. Open app with location access such as OrganicMaps, verify apps shown as using location
2. No more regular in background location indicators from UnifiedNlp, or Nearby
