idmap_autorid: fix traversal of ranges to correctly exclude mapping records.
When listing all ranges with "net idmap get ranges", the database records of the form "S-1-5-10" --> "GID 100016" were treated here as rangee mapings, resulting in an faulty printout like this: "RANGE 541346119: S-1-5-10". This patch fixes this by adding a filter that checks the size of the value datablob.
