Fix error in 'ip netns' parsing
Sometimes when doing worlddump would see a command line like this:
sudo ip netns exec (id: ip addr
This would cause an error to be seen in console.log:
2017-02-07 00:03:03.659570 | /bin/sh: 1: Syntax error: "(" unexpected
This is caused by there sometimes being extra data returned from the
'ip netns' command [1]. For example it might look like:
qrouter-0805fd7d-c493-4fa6-82ca-1c6c9b23cd9e (id: 1)
qdhcp-bb2cc6ae-2ae8-474f-adda-a94059b872b5 (id: 0)
