iputils: install ping, ping6, traceroute6 with setuid root

[ghost]

these utilities need to run with uid 0 to be useful. Thus,
install them setuid root like other distros do, too.

Out of curiosity, is this something you use?
It's very outdated (compared to upstream) so please update if you can.

I use it for the packaging of backuppc (see openwrt/packages#5886). I did not want to run backuppc as root, so it runs as a user "backuppc". Before starting a backup, backuppc runs ping to check if the client host is alive. "ping" in busybox also needs uid 0, but setting the uid bit on busybox is not an option. So I chose to depend on iputils-ping and make it setuid root, like e.g. debian does it. I assumed for someone installing backuppc, which obviously needs a lot of storage to be useful, generously added dependencies wouldn't be problematic.

Anyway, I'll see to updating this to current upstream

Hm. It seems, the newest version needs (or at least would like to have) libcap and libidn. These are in openwrt/packages. Can I depend on those or would that mean to either move libcap and libidn to openwrt/openwrt or to move iputils to openwrt/packages?

If you need external packages I'd suggest that you move it to the packages repo instead. Also please update to a more recent version. https://github.com/iputils/iputils

@nonicknamewasleftforme You should use $(INSTALL_SUID), if you're fixing some of the utils, what about the others like arping etc.? Could you please provide fix for complete package? Once done, please ping me back, I'll test it.
