hdv1394src: Make it possible to select a camera by its GUID

Browse source 
The source hdv1394src has the guid property that permits select a camera
connected from its GUID number.
However when this property is setted the selected camera is not changed.
The source continues using the default camera.

This problem was solved using the function iec61883_cmp_connect.
The reference for the function could be found here:
http://www.dennedy.org/libiec61883/API-iec61883-cmp-connect.html

The solution came from dvgrab source code.
