libcamera: media_object: Set devnode in MediaEntity

Browse source 
The MediaEntity::setDeviceNode() function was designed to set the device
node path associated with a MediaEntity. The function was there, but the
devnode_ member field was never actually set. Fix this.

While at there add a getter method for the devnode_ member as it will
soon be used.
