pco: fix encoding of fred's s0abs bit

Browse source 
The s0abs bit in the encoing of fred instruction is wrongly set to the
status of .neg modifier instead of .abs modifier.

Fix this copy-n-paste error.

Fixes GLCTS tests when running on top of Zink:
dEQP-GLES2.functional.shaders.random.trigonometric.vertex.4
dEQP-GLES2.functional.shaders.random.trigonometric.vertex.45
dEQP-GLES2.functional.shaders.random.trigonometric.fragment.4
dEQP-GLES2.functional.shaders.random.trigonometric.fragment.45
