[Test] Fix the wrong subsitution of `swift-frontend-target` in tests There is no `%swift-frontend-target` subsitution in test, which is actually `%target-swift-frontend`. The wrong spelling is actually interpreted by lit as `%swift`-frontend-target, and surprising didn't break any tests as the last argument from subsitution is `-define-availability` so it just leads to an very akward availability definition.
