Fix the following warning:
error: ‘void QFileDialog::setConfirmOverwrite(bool)’ is deprecated: Use setOption(DontConfirmOverwrite, !enabled) instead [-Werror=deprecated-declarations]
Note in the change that "false" changes to "true" because the option
is *Dont*ConfirmOverwrite.
QFileDialog::setConfirmOverwrite() is obsolete at least since 4.8
and QFileDialog::setOption() is available since 4.5 [1].
