util/cbfstool: Fix build in 32-bit userspace
Fix regression from commit 0dcc0662f3 util/cbfstool: Introduce
concept of mmap_window.
Use of region_end() wraps around at 4 GiB, if utility is run in
32bit userspace. The build completes with an invalid coreboot.rom,
while one can find error message in stdout or make.log:
E: Host address(ffc002e4) not in any mmap window!
