[KPhotoAlbum] error compiling in Ubuntu 16.04 and Mint 18.3

[Johannes Zarl-Zierl]

Hi Andreas,

The relevant difference is the version of Qt: OpenSUSE leap 42.1 still has Qt 
5.5 (leap 42.2 and Mint 18.3 probably as well).

I've patched KPA to compile with Qt 5.5 again (we already have similar patches 
in a few places).

Since you have probably more experience with OpenSUSE leap than me: Do you 
know which version of leap introduces a newer Qt version?
For now, supporting Qt 5.5 does not pose a problem, but eventually it might 
become a burden...

Cheers,
  Johannes
