[OE-core] [PATCH] usbutils: Split out lsusb.py

[Martin Hundebøll]

The pretty-printing "lsusb.py" script shipped by usbutils is currently
useless, as it doesn't runtime depend on python, and has unversioned
python in the shebang.

Avoid adding a python dependency to current configurations with usbutils
buy splitting lsusb.py into a usbutils-python package, and make it
runtime depend on python3-core.

Make the script usable by replacing the shebang with a direct call to
${bindir}/python3.
