Propagate runfiles for singlejar.

Since the singlejar toolchain attribute is currently defined as a single file and carried around as an Artifact instead of a FilesToRunProvider, it's not possible to implement it as a wrapper script that dispatches to an actual implementation somewhere in its runfiles. This would be useful to experiment with cross-platform action sharing.
