bugfix in frameworks vital for 5.13

[Marco Martin]

Hi all,
about https://bugs.kde.org/show_bug.cgi?id=394134 which makes many new kcms 
look borked, the problem actually wasn't the upstream qt bug (which is an 
issue as well)
but another one which was actually in qqc2-desktop-style
now, since released frameworks is the one that 5.13 has to depend, how to 
proceed, respin the tarball?

the commit that's needed is 
https://commits.kde.org/qqc2-desktop-style/
