Title:  mk/cfg: add .mk suffix on files to avoid "supprises" when backup files (mk/cfg/*~) are in mk/cfg/*

Right now we'll end up globbing them into the accepted targets and (ever worse) they will override the make variables of real target files because we `include`d everything in that directory.

As a side effect, we also editors get a better hint on file types.
