elm_map: add copyright_cb for osm tile source. 

Summary:
 - According to Copyright and license in Openstreetmap
   (https://www.openstreetmap.org/copyright/en)
   credit has to be in the corner of map.
 - Add copyright_cb which returns an object to show copyright.

Test Plan:
1. Excecute elementary_test->map
           2. Right click->source->set any tile source
           3. Observe copyright is added.
