[PATCH v2 4/6] configure: Introduce new jxrlib dependency.

[Rémi Bernon]

This library is the JPEG-XR / Windows Media Photo / HD Photo reference
implementation from Microsoft, released under BSD 2-Clause license:

https://archive.codeplex.com/?p=jxrlib

It is available for most Linux distributions already, and is also an
optional dependency for imagemagick, freeimage or calibre:

* https://packages.debian.org/source/sid/jxrlib

* https://rpmfind.net/linux/rpm2html/search.php?query=jxrlib

* https://packages.ubuntu.com/source/xenial/jxrlib

* https://www.archlinux.org/packages/community/x86_64/jxrlib/
