freedreno/ir3: disable cp for indirect src's

The variable-indexing tests always had a few random fails, which I
usually couldn't reproduce when running tests manually.  Somehow
recently this got a lot worse.  I ported a couple of the shaders to
GLES to see what blob does, and it also seems to be avoiding to cp
indirect srcs.  So I guess indirect w/ instructions other than cat1
(mov) are not totally reliable.  Let's just switch that off until
this is better understood.
