Migrate libraries to AndroidX (#458)

* Manifest: Add "android:requestLegacyExternalStorage="true""

(fixes #457) - I know this is not the fix everyone wants but it keeps Syncthing-Fork alive a little longer. See issue #457 to know why.

* Migrate to AndroidX

* Revert "Manifest: Add "android:requestLegacyExternalStorage="true"""

This reverts commit 7089be89beebd5ec95c9b2fac08d20f65d4da171.
