gst: Add function to disable certain video decoders
A number of hardware accelerated video decoders won't work for non-GUI
uses as they might require a display to work, such as VA-API, Broadcom's
MPEG decoder, etc.
This function is code that was already in the thumbnailer code, so we
can also apply it to the properties code.
