[PATCH] Add include for offsetof macro

[Stefan Assmann]

kexec/arch/i386/kexec-elf-x86.c and kexec/arch/x86_64/kexec-elf-x86_64.c
both use the macro offsetof() which according to the man page requires
#include <stddef.h>.
The include is not present at the moment and this patch adds it. This is
necessary for compatibility with i.e. uClibc.
