build: do not build runfile trees unnecessarily

Do not build runfile tree unnecessarily. Only if they
are needed, Bazel will create the runfile trees now.

This helps speeding up CI as we currently spend significant
amount of time unnecessarily with building these tree's for
cached and passing tests.
