libpayload: cbfs: Fix CBFS max size calculation. 

Cherry-picking CBFS fix from http://review.coreboot.org/#/c/2292/

For x86, the old CBFS search behavior was to bypass bootblock and we should keep
that.  This will speed up searching if a file does not exist in CBFS.
For arm, the size in header is correct now so we can remove the hack by
CONFIG_ROM_SIZE.
