[Buildroot] [git commit branch/2017.11.x] iputils: fix ping and traceroute6 executable permissions

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=371d7e8495a46d800c4c7322c5c1d09612ed181c
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.11.x

The iputils executables are installed without the setuid bit set,
which prevents some programs from working.

This patch adds a permission table to fix the permissions of the ping
and traceroute6 executables.
