freedreno/a6xx: Copy stencil as R8_UINT

Browse source 
Blitter does support it after all. Previous attempt to use R8_UINT
failed because we overwrote the a6xx format in emit_blit_texture(),
but some of the later setup still looked at the gallium format.

If we overwrite it in the pipe_blit_info before we even call into
emit_blit_texture() it works properly.
