[build] Replace obsolete makerom.pl with quick script using Option::ROM

The only remaining useful function of makerom.pl is to correct the ROM
and PnP checksums; the PCI IDs are set at link time, and padding is
performed using padimg.pl.

Option::ROM already provides a facility for correcting the checksums,
so we may as well just use this instead.
