Reproduction for oci_load bug

[alexeagle]

Run with:

bazel run //examples/assertion:case12_run

This should be closed. As we discussed on Slack, I needed to add the runfiles incantation at the beginning of my sh_binary target, to ensure that the rules_oci-generated load script (that it calls) will find its runfiles. Then everything works.

Surely, this is a yet undocumented change, but could be expected in the Bazel world.

Closing this as there's nothing to fix.
