util/cbfstool: Qualify struct e820entry as packed

In order to accord with grub (see include/grub/i386/linux.h) and
comments for offsets of members of struct linux_params,
struct e820entry should be defined as __packed, otherwise,
sizeof(struct linux_params) will become 4224 (0x1080).

Fortunately, the affected area is usually not occupied.
