KF5 drop KF5FilePicker::execute

To prevent calls to Qt5FilePicker::updateAutomaticFileExtension,
it is simply made virtual with an empty override. This is needed,
because the KF5 file picker has its own automatic extension
handling.

The main motivation is the fix for tdf#129071, which will result
in some major changes to XExecutableDialog::execute, so this will
prevent larger code duplication later.
