Fix fbjni packaging, exclude for publishing, include by default (#26995)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/26995
Fix current setup, exclude fbjni - we can not use independently pytorch_android:package, for example for testing `gradle pytorch_android:cAT`
But for publishing it works as pytorch_android has dep on fbjni that will be also published
For other cases - we have 2 fbjni.so - one from native build (CMakeLists.txt does add_subdirectory(fbjni_dir)), and from dependency ':fbjni'
We need both of them as ':fbjni' also contains java classes
As a fix: keep excluding for publishing tasks (bintrayUpload, uploadArchives), but else - pickFirst (as we have 2 sources of fbjni.so)
# Testing
gradle cAT works, fbjni.so included
gradle bintrayUpload (dryRun==true) - no fbjni.so
Test Plan: Imported from OSS
