i965: Drop _NEW_TRANSFORM from 3DSTATE_VS atom on Gen7.

The atom that uploads push constants listens to _NEW_TRANSFORM for
legacy clip plane handling.  On Sandybridge, the gen6_vs_state atom
emits 3DSTATE_CONSTANT_VS as well as 3DSTATE_VS, so it needs to listen
to the same set of conditions.

However, it looks like Gen7 doesn't need this.  The push constant atom
emits 3DSTATE_CONSTANT_VS directly, and the gen7_vs_state atom that
emits 3DSTATE_VS doesn't have a dependency on ctx->Transform.
