net-tools: backport a patch from upstream to use the same ifconfig format as debian/ubuntu

* this is needed for python3-ifcfg to parse it correctly
  https://github.com/ftao/python-ifcfg/issues/43
* backport this single patch, so it can be backported to dunfell
  then for master we should upgrade to new snapshot from debian
  which includes other fixes and improvements as well
* this is already part of net-tools_1.60-26.diff from debian we're using
  but it's first added there and then removed
  $ grep 'sprintf(flags' net-tools_1.60-26.diff
  ++    sprintf(flags, "flags=%d<", ptr->flags);
  +-    sprintf(flags, "flags=%d<", ptr->flags);
