test: ignore integration test TestCopyFileMaxTransfer on Google Drive

The test fails because it expects a copy with MaxTransfer and CutoffModeHard should
return fatal error, because this is thrown from accounting (ErrorMaxTransferLimitReachedFatal),
but in case of Google Drive the external google API catches and replaces it with a
non-fatal error:

pw.CloseWithError(fmt.Errorf("googleapi: Copy failed: %v", err))
