[LTP] [PATCH 2/9] tst_net.sh: Check for disabled IPv6 in legacy tests

[Petr Vorel]

Before tests timeout:

    # ./tcpdump01.sh -6

    tcpdump01 1 TINFO: initialize 'lhost' 'ltp_ns_veth2' interface
    tcpdump01 1 TINFO: add local addr 10.0.0.2/24
    tcpdump01 1 TINFO: initialize 'rhost' 'ltp_ns_veth1' interface
    tcpdump01 1 TINFO: add remote addr 10.0.0.1/24
    tcpdump01 1 TINFO: Network config (local -- remote):
    tcpdump01 1 TINFO: ltp_ns_veth2 -- ltp_ns_veth1
    tcpdump01 1 TINFO: 10.0.0.2/24 -- 10.0.0.1/24
    tcpdump01 1 TINFO: fd00:1:1:1::2/64/ -- fd00:1:1:1::1/64/
    tcpdump01 1 TINFO: start ping6 in background
    tcpdump01 1 TINFO: running tcpdump...
    (timeout)

With this patch:
    tcpdump01 1 TINFO: initialize 'lhost' 'ltp_ns_veth2' interface
    ...
    tcpdump01 1 TCONF: IPv6 disabled
