gst-validate-transcoding: add signal handling and issues printing

Browse source 
Update to have the same features as gst-validate.

1) Handle interrupts properly, with the additional of having the
'eos-on-shutdown' argument that sends EOS to the pipeline. This is
very useful for transcoding processes to finish correctly.

2) Print issues on the end of application
