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"
error.
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.
