[PATCH] iperf3: update to version 3.1.5 and download via git

[Christian Lamparter]

"This version of iperf3 makes some improvements to the
fair-queue-based pacing and improves the selection of
the default UDP packet size. Users who use either of
these aspects of iperf3 are encourage to review the
release notes for this version."
<http://software.es.net/iperf/news.html#iperf-3-1-5-released>

This patch also changes the package to download the
source via github <https://github.com/esnet/iperf>.
This also allows to switch to xz and save a couple of
KiB on the mirrors for every new release.

Alternatively, the project's homepage also provides a
iperf-3.1.5.tar.gz <http://downloads.es.net/pub/iperf>.
In this case all that needs to be updated is
