[db] do not rely on __gc for font object lifetimes
The penalty for having font object closed automatically is huge: It
takes around nine seconds more to rebuild the font database: 58 s with
__gc, 49 s by closing manually. Even if it’s not the default, we
reintroduce the code for closing fonts manually to avoid that situation.
