app: in gimp_gegl_apply_cached_operation(), don't dup src buffer for point ops

Browse Source 
In gimp_gegl_apply_cached_operation(), when the source and
destination buffers are the same, avoid duplicating the source
buffer when the applied operation is a point operation, since
applying it in chunks from/to the same buffer is not a problem in
this case.
