bootconfig: Move BOOTCONFIG_FOOTER_SIZE to include/linux/bootconfig.h
BOOTCONFIG_FOOTER_SIZE was defined locally in tools/bootconfig/main.c.
Move it to include/linux/bootconfig.h so that it can be shared with
the kernel and user-space tools. Also, use it in init/main.c instead
of the hardcoded (BOOTCONFIG_MAGIC_LEN + 8) expression when checking
the initrd size.
