[FIX] util/domains.py: Restore compatibility with 7.0

Importing util leads to importing everything from util/domains, including
`ignore()` from opernerp.tools.misc which got introduced after 7.0.

We change the ignore import to fallback to None if not found, so that the
rest of the util import can continue (like we already do in for the ofields
import in orm.py, introduced in e321b12).

closes #7
