[tests/ffi] Reinstate deleted test
Test was added in https://dart-review.googlesource.com/c/sdk/+/132843, duplicated in https://dart-review.googlesource.com/c/sdk/+/132604, and then got deleted in the non-NNBD folder, but that does not show up in https://github.com/dart-lang/sdk/commits/master/tests/ffi_2. Change-Id: Id3dbe2c065d3b74144f1007d35c8d4c8d962f528 Cq-Include-Trybots:dart/try:vm-ffi-android-debug-arm-try,vm-ffi-android-debug-arm64-try Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/161487 Auto-Submit: Daco Harkes <[email protected]> Commit-Queue: Daco Harkes <[email protected]> Commit-Queue: Martin Kustermann <[email protected]> Reviewed-by: Martin Kustermann <[email protected]>
