Add exclude-shared-libraries option to android_apk

This will allow Android APK targets to provide a list of shared
libraries to not link into Java. This can occur when a native
dependency includes a .so file as a runtime dep but does not
actually depend on it at link time.

BUG=b:73008622
TEST=Build and run release target with specific exclude
