[PATCH] KAsan: support including header from PBL

[Ahmad Fatoum]

It can be sometimes useful to add manual poisoning with KASAN to track
down errant accesses. This is complicated a bit, because some files are
build for both PBL and barebox proper. To make such debugging easier,
let's allow <linux/kasan.h> to be included from PBL code.
