Subject: [PATCH] genpolicy: disable env variable verification

Disable env variable verification to unblock CI, until container
images that don't specify the Env variables will be handled correctly
(see #9239).

Also, mark the image config Env field as optional, thus allowing
policy generation for these container images.

Fixes: #9240
