ci: uprev piglit 2022-08-30

Overall improvements: fewer crashes and failures due to improvements to the piglit.

Only two failures were encountered:

• #7152 (closed) (gl_culldistance failing everywhere)
• #7154 (closed) (virgl regression)
• on radeonsi-raven arb_shader_draw_parameters@drawid-single-draw-display-list moved from fails to flakes
• venus: #7093 (closed) sometimes happens (not related to this MR)
