[LTP] [PATCH v4 3/3] tst_net.sh: Require veth for netns (again)

[Petr Vorel]

new error message is more informative:
tcp_fastopen_run 1 TCONF: veth driver not available

then the old one:
Error: Unknown device type.
tcp_fastopen_run 1 TBROK: ip li add name ltp_ns_veth1 type veth peer name ltp_ns_veth2 failed

NOTE: originally added in 305a78e4c and temporarily reverted in
7fe2ad11d due problems which were fixed in commit
"lib: Fix kernel module detection on BusyBox".
