sandbox: add_image: support mmaping block devices on 32-bit hosts
BLKGETSIZE64 writes 64-bit to the address pointed at by the ioctl argument.
As hf->size is a 32-bit size_t on 32-bit systems, on such systems,
the adjacent member might be corrupted. Fix this.
Fixes: 8d6da6462b12 ("sandbox: add_image: mmap block devices")
