cooker: Drop sre_constants usage

As reported by Martin Jansa <Martin.Jansa@gmail.com>:

bitbake/lib/bb/cooker.py:16: DeprecationWarning: module 'sre_constants' is deprecated
  import sre_constants

it's deprecated since 3.11 with:

  python/cpython#91308

The correct replacement for our usage is re.error so use that instead.
