[Merge] lp:~chris.gagnon/kubuntu-packaging/enable-tests-qtimageformats-opensource-src into lp:~kubuntu-packagers/kubuntu-packaging/qtimageformats-opensource-src

[Dmitry Shachnev]

Thanks. I see no reason to diverge from Debian here, so I've committed the changes directly to Debian Git, with some (usual) fixes:

- Build-dependency on xauth;
- Using dh_auto_test to take care about DEB_BUILD_OPTIONS=nocheck;
- Removing some unneeded make variables, only plugins path is really helpful.
