cbfstool: set init_size for linux payloads.

We were not setting the init_size for linux payloads.
    A proper value of init_size is required if the kernel
    is x86_64.

This is tested in qemu and fixes the observed problem
    that 974f221c84b05b1dc2f5ea50dc16d2a9d1e95eda and later would not
    boot, and would in fact fail in head_64.S.
