cbmem utility: compatibility with older coreboot versions

Commit b8ad224 changed the memory address in lb_cbmem_ref coreboot
    table entries from a pointer to a uint64_t. This change was introduced
    to make the cbmem utility work on both 32bit and 64bit userland.
    Unfortunately, this broke the cbmem utility running on older versions
    of coreboot because they were still providing a 32bit only field for
    the address while the cbmem utility would now take the following 4
    bytes as upper 32bits of a pointer that can obviously not be
    mmapped. This change checks if the size of the lb_cbmem_ref structure
    provided by coreboot is smaller than expected, and if so, ignore the
    upper 32bit of the address read.
