KASAN and KCSAN are mutually exclusive on 7.0-rc3 kernel
(lib/Kconfig.kcsan: 'depends on ... !KASAN'). User picked
KASAN first. This script applies the KCSAN-only config delta
on top of the lockdep base for the follow-up build, so the
KCSAN config survives session-compacting.
Run AFTER the KASAN-pass test cycle completes, IF KASAN comes
up silent on the GPU-compositor wedge test.
