gdp: Fix Timmeke Waymans bug.

Original commit message from CVS:

* libs/gst/dataprotocol/dataprotocol.c (gst_dp_packet_from_caps):
Fix Timmeke Waymans bug.
(gst_dp_caps_from_packet): Make sure we pass a NUL-terminated
string of the proper length to gst_caps_from_string. There's a
potential for, before this fix, that this could cause someone
connecting over the network to cause a segfault if the payload is
not NUL-terminated.
