llvmpipe: fix edge-rule logic for lines

In 2737abb44ef, the handling of pixel-offsets and edge rules were
untangled, but one case was missed.

This fixes the following dEQP test-cases on VirGL + LLVMpipe
- dEQP-GLES2.functional.draw.random.10
- dEQP-GLES2.functional.draw.random.42
- dEQP-GLES3.functional.draw.random.105
- dEQP-GLES3.functional.draw.random.114
- dEQP-GLES3.functional.draw.random.135
- dEQP-GLES3.functional.draw.random.144
- dEQP-GLES3.functional.draw.random.155
- dEQP-GLES3.functional.draw.random.174
- dEQP-GLES3.functional.draw.random.206
- dEQP-GLES3.functional.draw.random.31
- dEQP-GLES3.functional.draw.random.43
- dEQP-GLES3.functional.draw.random.84
- dEQP-GLES31.functional.draw_indirect.random.20

...as well as these on Zink + Lavapipe:
- spec at nv_primitive_restart@primitive-restart-disable_vbo
- spec at nv_primitive_restart@primitive-restart-vbo_combined_vertex_and_index
- spec at nv_primitive_restart@primitive-restart-vbo_index_only
- spec at nv_primitive_restart@primitive-restart-vbo_separate_vertex_and_index
- spec at nv_primitive_restart@primitive-restart-vbo_vertex_only

Fixes: 2737abb44ef ("gallium: Replace gl_rasterization_rules with lower_left_origin and half_pixel_center.")
