i965/fs: Simplify gl_SampleMaskIn handling.

As far as I can tell, there's no point in allocating an extra register
and generating a MOV---we can just use the copy provided as part of our
thread payload directly.  It's already in the right format.

Of course, there are zero Piglit tests for this.  We don't actually ship
the extension (GL_ARB_gpu_shader5) that exposes this functionality
either.
