fix(jinja): omit_ip_address don't work on some platform

It apprears that the

  `if not (omit_ip_address is sameas true or host in omit_ip_address)`

always returns `True` on older Jinja platforms:

- default-ubuntu-1604-3000-3-py2
- default-ubuntu-1604-2019-2-py3
- default-amazonlinux-1-2019-2-py2

Each part of the `or` conditional need to be surrounded by parenthesis.
