Remove check 069

Fonttools runs some sanitization on load that catches wrongly set up loca tables and matches them to the glyf table.

#1821

I'd like to consider actually implementing this here, since someday we might want to get rid of third-party linters such as msfontval and fontforge. (see #1814 and #1541)

Would it be possible to detect the problem or does fonttools silently fix the problem on load with no chance of the user being noticed about it?

In all actuality, the sanitization is gone and ft logs errors when trying to access loca and glyf. Huh. On it.

Ok, it's still there but doesn't trigger due to lazy loading if you modify stuff and save the file before accessing certain tables.
