gst-plugins-good 0.10.17: depend on libv4l in order to fix a webcam

gst-launch v4lsrc ! jpegdec ! xvimagesink doesn't work if you don't
  depend on libv4l with my gspca webcam.
The fix was suggested in #gstreamer in freenode:
  Feb 20 20:37:36 <fargiolas>     GNUtoo: did you compile it on
   your own? it seems it's not compiled with libv4l support
  And:
  Feb 20 20:43:08 <fargiolas>     GNUtoo: probably your device
   output frames in an exotic pixel format and libv4l is needed
   to decode it
The webcam was a gspca_zc3xx webcam
