x86/kaslr: Fix build warning in KASLR code in boot stub
lib/kaslr.c is used by both the main kernel and the boot stub. It
includes asm/io.h which is supposed to be used in the main kernel. It
leads to build warnings like this with clang 13:
warning: implicit declaration of function 'outl' is invalid in C99 [-Wimplicit-function-declaration]
Replace <asm/io.h> with <asm/shared/io.h> which is suitable for both
cases.
