[Piglit] [PATCH] glean/tstencil2: adjust test to do what it says

[sroland at vmware.com]

From: Roland Scheidegger <sroland at vmware.com>

Comment is indicating it will decr stencil to 6 by stencil fail
But test was configured to incr stencil by sfail, in reality it worked
because it actually passed stencil and hence would use the zpass decr.
Change it to match comment, and change the other values a bit as well
(to make sure errors are caught when some implementation applies both
sfail and zfail (or zpass) ops, an error undetected so far in llvmpipe...)
