[LTP] [PATCH] containers: fix dev name in create_veth()

[LTP] [PATCH] containers: fix dev name in create_veth()

[Hangbin Liu]

The new version of iproute2 will show veth device like veth0@veth1, but we
won't get a dev proc entry like this. Fix the dev name to avoid error like
/proc/sys/net/ipv4/conf/veth0@veth1/proxy_arp: No such file or directory

It looks fine to me.

Hi!
I've just pushed complete rewrite of the testcases, please make sure
that netns testcases from latest git works for you.
