iputils: update to 20161105

We've been using obsolete upstream URI for quite a while; meanwhile
a lot of development has happened

Drop all the patches: they are either changing the code that has been refactored,
or are backports.

Add a new musl fix patch from gentoo.

ping6 and tracepath6 variants have been folded into standard versions.
