Subject: [PATCH net] selftests/net: in rxtimestamp getopt_long needs terminating null entry

From: tannerlove <tannerlove@...gle.com>

getopt_long requires the last element to be filled with zeros.
Otherwise, passing an unrecognized option can cause a segfault.

Fixes: 16e781224198 ("selftests/net: Add a test to validate behavior of rx timestamps")
