Blacklist GDEF tables of more fonts

This is based on bug reports that have been filed against Firefox since it
updated to a version of harfbuzz that uses zeroing by GDEF rather than by
Unicode. I'm sure there are a bunch more font versions that should also be
included; these are just the ones I have on hand and have confirmed as having
bad GDEF data.

Given how the list here is growing, I think we should reconsider the approach,
and perhaps revert to zeroing by Unicode instead.
