Use _resolve_wikidata in layer mapping.yaml (#731)

Mark all tables that should not be populated with the Wikidata
international labels with a special OMT-specific flag.

This should be ok to merge even before the new tools version
is used because imposm seems to ignore anything it doesn't understand.

The next tools version will remove it when generating imposm mapping file.
