cbfstool: Fix crash on image without bootblock in end of ROM.
On platforms with CBFS data filling end of ROM image without bootblock in the
end (ex, ARM), calculation of "next valid entry" may exceed ROM image buffer in
memory and raise segmentation fault when we try to compare its magic value.
To fix this, always check if the entry address is inside ROM image buffer.
Verified to build and boot successfully on qemu/x86 and armv7/snow.
