include/option.sh: fix i945 bootblock copy

it wasn't being copied right

the roms under elf/ were being copied, but not the ones
under bin/ - i need to audit it further

for now, i run modify_coreboot_roms from build/roms
instead of update/trees

so, the ones under elf/ no longer have bootblocks copied.
it's only done in bin/
