patch 9.1.0613: tests: termdebug test may fail and leave file around

Problem:  tests: termdebug test may fail and leave temp file around
          (Dominique Pellé)
Solution: only run balloon_show() if the function exists, validate
          termdebug is running using the g: termdebug_is_running var,
          use defer to delete temporary files

fixes: #15334
