config: parse_key_binding_section(): use provided action-map

Don’t call has_key_binding_collisions() with ‘binding_action_map’
unconditionally; use the provided ‘action_map’ instead.

This fixes wrong error messages for key combo collisions in key
binding sections other than the regular “key-bindings”.
