gst-player: support setting the video sink from environment var 

Also initialize the video sink to 'glimagesink' in case it has not been
configured from the environment, but only for the X11 application
(gtk-play). This recipe also provides a command line application for
framebuffer (gst-play) that is not affected by this change.

been set in the environment.
