kde5 fpicker: Reuse 'initialize()' from base class

Take over missing case from 'KDE5FilePicker::initialize' to
'Qt5FilePicker::initialize' and make
'Qt5FilePicker::addCustomControl' virtual, so that the
subclass's implementation is called in the 'initialize()'
method (in particular to avoid adding another autoextension
checkbox).

Drop the 'KDE5FilePicker::initialize' so that the
base class implementation is used, which now does the
same thing.

Add 'override' keyword in KDE5Filepicker.hxx.
