i965: Claim to support rendering to integer FBOs.
We're missing support for the software paths still, but basic
rendering is working.
v2: Override RGB_INT32/UINT32 to not be renderable, since the hardware
can't do it but we do allow texturing from it now. Drop the
DataType override, since the _mesa_problem() isn't in that path
any more.
