Pull up following revision(s) (requested by ozaki-r in ticket #117):

        tests/net/ndp/t_ndp.sh: revision 1.34

Make a permanet neighbor cache to avoid sending an NS packet disturbing the test

A receiver of an ICMPv6 request packet creates a stale cache entry and it turns
into the delay state on replying the packet.  After 5 second, the receiver sends
an NS packet as a reachability confirmation, which disturbs the test and causes
a unexpected result.

Should fix PR misc/54451
