[util] Fix up checksum in UNDI ROM header, if present

The UNDI ROM header does contain a checksum byte.  Apparently no-one
cares about this, since iPXE has left it as zero for years without
anyone noticing.

Since Option::ROM now understands the UNDI ROM header, we may as well
fix up the checksum byte for the sake of completeness.
