llvmpipe: fix position offset interpolation

pos offset only applies to the gl_FragPos input, when I refactored
I messed that up, only use pos_offset for the position inputs
and use 0.5 otherwise.

This fixes:
GTF-GL45.gtf30.GL3Tests.fragment_coord_conventions.fragment_coord_conventions_multisample
