[I/oracle][PATCH] UBUNTU: [Config] oracle: Disable KCSAN

[Krzysztof Kozlowski]

KCSAN reports several data-races when booted on Oracle instances (and on
other kernels as well). There are around 100 reports during boot, like:

    BUG: KCSAN: data-race in __mutex_lock.constprop.0+0xd0/0x750
    BUG: KCSAN: data-race in osq_lock / osq_lock
    BUG: KCSAN: data-race in tick_nohz_next_event / tick_nohz_stop_tick

Since main kernel has KCSAN disabled, remove it also from derivative.
