These conditions were added in 8cf89245f5
to account for old versions of debian/ubuntu (apparmor_parser < 2.8.96)
that lacked some options;
> This allows us to use the apparmor profile we have in contrib/apparmor/
> and solves the problems where certain functions are not apparent on older

Those patches were from 2015/2016, and all currently supported distro
versions should now have more current versions than that. Looking at the
oldest supported versions;
Ubuntu 18.04 "Bionic":
apparmor_parser --version
AppArmor parser version 2.12
Copyright (C) 1999-2008 Novell Inc.
Copyright 2009-2012 Canonical Ltd.
Debian 10 "Buster"
apparmor_parser --version
AppArmor parser version 2.13.2
Copyright (C) 1999-2008 Novell Inc.
Copyright 2009-2018 Canonical Ltd.
This patch removes the conditionals.
