run cra* err* only finds err1, not the other one...

[xparq]

UPDATE: The err* cases have been moved to FAIL*/fail* and cra* to ABORT*/Can't exec!

First of all, it correctly ends up as a directly specified case list (find can only handle a single pattern, I guess), but

• I'm not sure where the actual globbing happens (I think in run_test!), as BB has it disabled (dumping the list confirms: it's just the two unexpanded inputs), and
• it should be triggered explicitly before iterating the list with run_case.
