ci: run lavapipe at the AVX level on every Linux runner 

agc_driver_vopc_compare failed on every Linux runner with an
AVX512-FP16 Xeon (Sapphire, Emerald and Granite Rapids) and passed on
AMD EPYC and Ice Lake runners. Ubuntu 24.04's lavapipe compiles with
LLVM 20.1.2, which on these CPUs merges a masked fcmp ult/uge on half
vectors with the same compare of swapped operands, so v_cmp_nle_f16,
v_cmp_nlt_f16 and v_cmpx_nle_f16 return the result of their mirror.
The recompiler's SPIR-V is the same on every device and correct.

GALLIUM_OVERRIDE_CPU_CAPS=avx keeps LLVM off AVX-512, so every runner
compiles the tests the same way.
