Blackberry: Remove blackberry support

Keep QNX.

A short informal search did not turn up any more blackberry users,
even though there is interest in QNX. So this patch removes the
platform: We had no contact with the maintainers in months, there
are no changes going into the code for about as long.

I am not even aware of anybody testing the platform, so any
remaining users are probably better of with Qt Creator 3.2 or so
where the code was extensively tested.
