message: Fix a buildscript error which prevents macro being used by other workspaces
  Converting to label and back to string will prepend current workspace,
  e.g: "//tensorflow" -> "@org_tensorflow//tensorflow". Projects who
  integrate TensorFlow from another Bazel workspace, and use macros like
  tflite_copts() need the prefix.
  For more info please take a look at:
