[ITA] qrencode 4.1.1

[Lemures Lemniscati]

Hi!

ITA for qrencode (libqrencode) packages.

The upstream version of qrencode (libqrencode) is v4.1.1 [1], now.
It takes major update from current cygwin package v3.4.4.

A new candidate cygport file is placed at [2] (but it is not tested
on Cygwin AppVeyor CI, yet).

And generated package files are placed at [3] or [4].
