    cbmem utility: Use mmap instead of fseek/fread
    The kernel on Ubuntu 12.04LTS does not allow to use
    fseek/fread to read the coreboot table at the end of
    memory but will instead abort cbmem with a "Bad Address"
    Whether that is a security feature (some variation of
    CONFIG_STRICT_DEVMEM) or a kernel bug is not  yet clear,
    however using mmap works nicely.
