[LTP] [COMMITTED][PATCH] test_net.sh: fix adding IP addresses in netns setup

[Alexey Kodanev]

When running LTP network tests for the first time with ./network.sh -6,
netns setup function in test_net.sh tries to add IPv6 addresses twice
because '-6' option passed to test_net.sh too.

Fix it by explicitly setting TST_IPV6 in netns setup when adding IPv4
addresses.
