SI-7630 [Avian] Skip test run/repl-javap-outdir-funs on Avian

The test fails, because the REPL command reports that no anonfuns were
found. I have spent a considerable amount of time to figure out what's
the issue here with no success.

Skip it for now, so that we don't lose sight of the big picture.
