75ba7a9b32 Add "apparmor_parser" warning to check-config.sh 
If AppArmor is enabled on the current system, but "apparmor_parser" isn't installed, it causes all kinds of issues.

a59e1949b5 Update contrib/check-config.sh to check for CGROUP_FREEZER (which is newly required), and to use /proc/mounts for checking if we have a cgroup hierarchy instead of using /proc/$$/mountinfo (which on systemd might not list the cgroup hierarchy)
