QSaveFile is intended to be a replacement for QFile, and should use the
same permissions for newly created files. QTemporaryFile however creates
new files with 0600 mask by default.
Fix this by making the mode_t argument QTemporaryFileEngine uses
configurable, and using 0666 for QSaveFile (like we do in QFile).
[ChangeLog][Important behavior changes] Files created by QSaveFile do
now have the same rights as files created by QFile. This also fixes a
regression in QSettings: In the Qt 5.4 series, new files created by
QSettings were only readable by the current user.
Task-number: QTBUG-44086
