[PATCH 05/25] efw-downloader: efw-proto: add class virtual method to handle responded signal

[Takashi Sakamoto]

GObject allows applications to override class virtual method with own
method implementation in inheritance.

This commit adds the class virtual method to handle 'responded' signal
added in the former commit.
