scripts: kconfig: gnuconfig: Ignore loc

The commit 125d0da added 'loc' to the sym.ranges tuples and fixed
kconfiglib.py but guiconfig.py is left untouched. This make menuconfig to
die with:

  Exception in Tkinter callback

      range_info = _range_info(sym)
    File ".../scripts/kconfig/guiconfig.py", line 1339, in _range_info
      for low, high, cond in sym.ranges:
          ^^^^^^^^^^^^^^^
  ValueError: too many values to unpack (expected 3)

This commit ignores the last element in the tuples.
