[Debian-med-packaging] Bug#805087: Please change the qt5 suffix from -qt5 to 5

[Stefan Ahlers]

Hi Andreas,

I've updated the debian files and I decided to use quazip 0.7.1 and
patch the CMakeLists.text files instead of using a development release.

Furthermore, I was not able to install the FindQuaZip.cmake file,
because it is not allowed to ship a "Find module". (lintian error:
https://lintian.debian.org/tags/package-contains-cmake-private-file.html).

I've also added a new package called libquazip-qt5-headers to provide
the headers for the Qt5 library.

I hope I have uploaded the changes correctly to the git repository. For
me the package works, please test the changes.

Kind regards,
Stefan
