Fix the proc integration test & include missing AA profile

Browse source 
Integration tests were failing due to proc filter behavior
changes with new apparmor policies.

Also include the missing docker-unconfined policy resolving
potential startup errors. This policy is complain-only so
it should behave identically to the standard unconfined policy,
but will not apply system path-based policies within containers.
