To go with all the other load methods, and many boot scripts' expectations, also store the size of the file loaded last in the environment variable "filesize". We first put the kernel size in there, but overwrite this with the initrd size, should we have one, because this is probably the more prominent user of $filesize (in the booti or bootz command).
