scripts: Add oe-pylint

Add an oe-pylint wrapper around pylint3 to run static analysis on our python
codebase. For now display errors and exclude common warnings which are not
applicable to our codebase.

The aim is to start generating this report on the autobuilder and to
improve our score over time.
