Accepting request 598826 from home:cboltz

- create and package precompiled cache (/usr/share/apparmor/cache,
  read-only) (boo#1069906, boo#1074429)
- change (writeable) cache directory to /var/cache/apparmor/ - with the
  new btrfs layout, the only reason for using /var/lib/apparmor/cache/
  (which was "it's part of the / subvolume") is gone, and /var/cache
  makes more sense for the cache
- adjust parser.conf (via apparmor-enable-profile-cache.diff) to use both
  cache locations
- clear cache also in %post of abstractions package
