Make hard link for EOS swath datafield.
  - update expected results

Each SWATH has two groups: Datafield and Geolocation field, and they share the same dimension. Due to the restriction of netCDF4, dimension should be located in both Datafield and Geolocation field. So, put a hard link for each dimension so that the dimension can be read from both Datafield and Geolocation field.

Expected results were regenerated. All expected results (except two cases: swath_tll, swath_tll02 which have too complex structure) should be read by ncdump. Under kagiso, I could see all files except two cases were properly printed with ncdump.
