[PATCH] checkpatch: explicitly require python3 for codespell

[Alexander Lobakin <alexandr.lobakin@intel.com>]

Fix a bug where checkpatch couldn't automatically find
dictionary.txt.
"Unversioned" `which python` might be not present in a system
with Python 3 and codespell installed and working. SPDX check
already refers to `which python3`, do the same for codespell.
