rng: make opened property read-only

The ``opened=on`` option in the command line or QMP ``object-add`` either had
no effect (if ``opened`` was the last option) or caused errors.  The property
is therefore useless and was deprecated in 6.0; make it read-only now.

``opened`` property of ``rng-*`` objects (since 6.0)
''''''''''''''''''''''''''''''''''''''''''''''''''''
The only effect of specifying ``opened=on`` in the command line or QMP
``object-add`` is that the device is opened immediately, possibly before all
other options have been processed. This will either have no effect (if
``opened`` was the last option) or cause errors. The property is therefore
useless and should not be specified.
