Delete erroneously test not updated with dwarf verification JSON change (#126587)

Between a PR (124936) adding a base test for dwarf verification JSON
output and a modification of the same in changing the JSON (125062),
there ended up being two versions of the test. The base one and the
fixed one, when there should be only one copy. The base fails as the
JSON format has changed, so deleting that version.
