The current mtr does not build if IPv6 is disabled globally, add a patch to
fix the build in this case.

Switch the mtr package to the upstream `newdns` git branch.

This will fix compilation on Glibc, uClibc and musl without requiring
further patches.

Note that the base version of this branch is 0.85, not 0.86 so the
lower version number is intentional.
