cbfstool: Fix initial empty space in image creation.

When calculating initial CBFS empty entry space, the size of header itself must
    be not included (with the reserved space for entry name). This is a regression
    of the old cbfstool size bug.

Before this fix, in build process we see:
     OBJCOPY    cbfs/fallback/romstage_null.bin
     W: CBFS image was created with old cbfstool with size bug.
        Fixing size in last entry...

And checking the output binary:
     cbfstool build/coreboot.pre1 print -v -v
     DEBUG: read_cbfs_image: build/coreboot.pre1 (262144 bytes)
     DEBUG: x86sig: 0xfffffd30, offset: 0x3fd30
     W: CBFS image was created with old cbfstool with size bug.
        Fixing size in last entry...
     DEBUG: Last entry has been changed from 0x3fd40 to 0x3fd00.
     coreboot.pre1: 256 kB, bootblksz 688, romsize 262144, offset 0x0 align: 64
     Name                           Offset     Type         Size
     (empty)                        0x0        null         261296
     DEBUG:  cbfs_file=0x0, offset=0x28, content_address=0x28+0x3fcb0

After this fix, no more alerts in build process.
    Verified to build successfully on x86/qemu and arm/snow configurations.
