[KPhotoAlbum] Patch to use the right database driver

[Tobias Leupold]

>From the latest docs (Qt 5.10), cf. http://doc.qt.io/qt-5/qsqldatabase.html :

QSqlDatabase::QSqlDatabase(const QString &type)

The currently available driver types are:
..
QSQLITE     SQLite version 3 or above
QSQLITE2    SQLite version 2
..

So apparently, using "QSQLITE" seems to be the right thing (and "QSQLITE3" is 
not listed) ... can you explain where you have your information from?
