scripts/spdxcheck.py: Fix path to deprecated licenses

The directory name for other licenses was changed to "deprecated" in
commit 62be257e ("LICENSES: Rename other to deprecated"). But it was
not changed for spdxcheck.py. As result, checkpatch failed with

  FAIL: "Blob or Tree named 'other' not found"
  Traceback (most recent call last):
