Fix CI breakage due to PR collision

PR containers#7633 disallowed "-l" (--latest) with container args.

PR containers#7630 made changes to the "podman wait" command. The error
message it issues is inconsistent (and incompatible) with
the one required by the new BATS --help test. Fix that.

This is entirely my fault. I was aware of containers#7630, and I was
careful to check the output message format, but I was not
careful enough (I trusted my eyes, not my code).
