Unfortunately there's no python bindings for this tool. AFAIK you can either 
use the QgsMapToolEmitPoint tool or build your own tool class on the abstract 
QgsMapTool (the latter is what I would do - take the clickfu or profiletool 
plugins as an example) and then use the coordinates to find features.
