QPrintSupport: do not bypass a base class' virtual

QAbstractPrintDialog (a QDialog subclass) has an interesting
override of exec(): a pure virtual, without a body.
The UNIX subclass was therefore forced to override it, but
since it did not need to do anything with it, it had to call
QDialog::exec (bypassing the direct base, otherwise it
would cause a pure virtual call).

Eliminate the pure virtual override. This should be BC;
the layout of the vtable does not change, merely its contents.
