1.12.58: archetype/final should be optional

[jouvin]

Currently the broker created profiles where the last line is include { "archetype/final" };. I can imagine that the this template is not necessarily needed and rather than creating it empty, I'd suggest that this line is replaced by:

include if_exists('archetype/final');

Note that an optional template is still part of the dependency information, so if it is added later, it will cause the profiles to be recompliled.

It's pretty much essential for all normal use-cases (it's the only safe way to force profile content), but I see your point.

After more experience with Aquilon and a discussion with @urbonegi , I agree that these templates have to exist in a real configuration and that it is better to expose that they are missing.
