[WIP] apparmor: update to 3.0.0
+ builds and works fine for x86_64-glibc

- [ ] doesn't build for musl yet and I am not experienced enough to fix it
- [ ] should I bump libapparmor.so in common/shlibs?
- [ ] this update breaks compatibility with older apparmor profiles, are there any which have to be fixed?
