apk: Include recursive libraries via gradle as well
Browse files Browse the repository at this point in the history 
The `gradle` build was only including the target library from `cargo`,
but not any (in)direct dependencies like `libc++_shared.so`.

Move the logic where we recursively scan all libraries, and pass
the result to the `gradle` builder in addition to the existing `apk`
builder.
