t_client.sh: ignore fields from "ip -6 route show" output that distort results.

"ip -6 route show" prints stuff like "rtt 38ms rttvar 38ms cwnd 10", which
sometimes changes while an OpenVPN test is running, resulting in spurious
failures in the "ifconfig/route must be restored identically after
OpenVPN ends" test in t_client.sh.  Not all fields are there all the time,
so use "sed" to get rid of whatever is printed this time.

Only relevant for "make check" on linux builds with "--enable-iproute2".
