.checkpackageignore: remove chromebook check-hash exceptions

Commits 3988f2d9238bc027b5d16219867e8d3c701c0c06 and
0d91281d7bdfa09be28237bab694e6ac22466541 added hashes for the chromebook
defconfigs, but forgot to remove the exception from .checkpackageignore.

Regenerate .checkpackageignore, which removes those exceptions.
