optionrom: fix bugs in signrom.sh
signrom.sh has multiple bugs:
- the last byte is considered when calculating the existing checksum, but not
when computing the correction
- apprently the 'expr' expression overflows and produces incorrect results with
larger roms
- if the checksum happened to be zero, we calculated the correction byte to be
256
Instead of rewriting this in half a line of python, this patch fixes the bugs.
