[OE-core] [PATCH 1/2] kernel.bbclass: do_sizecheck: update path to build image

[michel.thebeau at windriver.com]

From: Michel Thebeau <michel.thebeau at windriver.com>

KERNEL_OUTPUT is a path relative to ${B}, and resolves to a soft
link to ${B}/${KERNEL_IMAGETYPE}.  When do_sizecheck runs it
does not find the file, and does not fail.

So check the size of ${B}/${KERNEL_IMAGETYPE}.

Alternative approaches to resolve this could be:
 - check ${B}/${KERNEL_OUTPUT}, with ls -L to resolve the link
 - check ${B}/${KERNEL_OUTPUT}.bin

This is related to, but does not resolve:
