west.yml: Update ci-tools to treat all .py files as Python

Get commit 343b5c7 ("check_compliance.py: Treat all .py files as Python
in pylint check") in.

libmagic doesn't consider the filename, and mis-detects kconfiglib.py as
HTML for example. Treat all files ending in .py as Python, and only use
libmagic for other files.
