srd: onewire: Fix incorrect format for annotation output.

Should be a list containing:

 - Annotation format number (e.g. 0, or ANN_DEC, etc).

 - A list of strings (the annotation). If more than one string is
   supplied, the other ones should be short versions of the string.
   Example: [ANN_DEC, ["Foobarbaz", "Foo", "F"]]

   This is optional, and mostly useful for GUIs.
