Kotlin library ABI jar sometimes not available for friend_paths config

Created by: jbarr21

In some cases, the Kotlin ABI jar will not be available in order to be used to configure the friend_paths.

If the ABI jar target exists (which it always does for Kotlin), then shouldn't we just add a required rule so that we can wait for it to be generated instead of falling back to the original non-ABI source jar?
