remove flutter attach devicelab test (#62704) 

The flutter tool already has an attach integration test: https://github.com/flutter/flutter/blob/master/packages/flutter_tools/test/integration.shard/flutter_attach_test.dart

The devicelab test frequently fails with difficult to debug issues and is not worth the maintenance cost.
