David Gibson ada08d4735 tests: Remove unnecessary truncation of temporary files in udp tests
All the UDP tests use :> to truncate some temporary data files.  This
appears to be so that they're empty before writing data to them with tee.
However tee, by default, truncates its output file anyway (you need tee -a
to append).  So drop the unnecessary truncations.
