[LTP] [PATCH 2/2] network/in6_02: Don't use default value for LHOST_IFACES

[Petr Vorel]

in6_02 can be test without help of network.sh. In that case LHOST_IFACES
is not defined and "eth0" is used as default value. This can cause
failures.

I'm not sure if we can make all C network tests make independent on
loading variables via tst_net.sh, but here it does not make much sense
to me to fail when it's not done.
