output/alert: rewrite code for app-layer properties

Browse Source 
Especially fix setup-app-layer script to not forget this part

This allows, for simple loggers, to have a unique definition
of the actual logging function with the jsonbuilder.
This way, alerts, files, and app-layer event can share the code
to output the same data.
