[Buildroot] [PATCH 1/1] iputils: set the permissions with IPUTILS_PERMISSIONS

[Petr Vorel]

for arping, clockdiff and ping. These require root permission for
socket(). Upstream solution (script setcap-setuid.sh) requires
setcap binary on the host and cap_net_raw+ep + libcap or setting
setuid root executable which is dangerous).

This restores behavior used for version s20180629 (which was used
for ping and traceroute6, but we don't build traceroute6 since s20190515).

Hi,

it'd be great also create symlink ping -> ping6, but don't know how.

Kind regards,
Petr
