Patch for rtph265pay to fix a bug in parsing nal unit type.

The nal unit type is incorrectly parsed in rtph265pay. As a result, VPS, SPS,
and PPS are not detected and will not be periodically inserted when setting
"config-interval" to a non-default value (e.g., 1). As a result, starting the
sender before the receiver does not work. This is fixed with this very simple
patch.

Example sender pipeline:

gst-launch-1.0 videotestsrc ! queue ! x265enc tune=zerolatency
speed-preset=ultrafast ! queue ! rtph265pay config-interval=-1 ! udpsink

Example receiver pipeline:

gst-launch-1.0 udpsrc ! application/x-rtp, payload=96 ! queue ! rtph265depay !
h265parse ! queue ! avdec_h265 ! queue ! videoconvert ! xvimagesink
