Merge abstraction: add nameservice-strict.

Browse Source 
As I have read multiple MR mentioning the `nameservice-strict`. Therefore, I thought it would make sense to directly import it here.

To give some context, this abstraction is probably the most commonly included abstraction (after `base`). In `apparmor.d`, it is used by over 700 profiles (only counting direct import). Therefore, adding new rules can have an important impact over a lot of profiles.

Note: the abstraction is a direct import from https://gitlab.com/roddhjav/apparmor.d. The license is the same, I obviously kept Morfikov copyright line. However, I am not sure either or not the SPDX identifier can be used here.
