Ubuntu 19.10 (and latest Debian, openSUSE rolling releases) has AppArmor
2.13.3. Recommend to use latest AppArmor profile for these distribution
releases.
(cherry picked from commit fa86413b1b)
Ubuntu 19.04 was released with AppArmor 2.13.2 [0].
Update documentation to hint users that they can use AppArmor profile
with latest AppArmor features on Ubuntu 19.04 release.

AppArmor profile attachement example is wrong because it does not use {
} "alternations" to make comma define alternative executable path.
Update example to make it actually work in custom install prefix case.
security/apparmor/install.sh scripts does not need to `cd` into it's
directory to work correctly.
Simplify example to invoke `install.sh` without `cd`.
