gstv4l2bufferpool: handle -EPIPE from DQBUF to signal EOS

At the media summit at ELC-E 2014, we agreed that for mem2mem decoders,
additionally to setting a (not yet specified) flag for the last buffer,
VIDIOC_DQBUF should return -EPIPE after the last buffer has been dequeued on
the capture queue. We can use this in the V4L2 decoder to signal EOS after
-EPIPE was received.
