sub: remove logic for disabling hinting on scaled EOSD

This was an extremely obscure setting, as it was used only with vo_gl
if its scaled-osd suboption was used. If you really want this, you can
set the desired ass-hinting value directly, and there will be literally
no loss in functionality.

Note that this didn't actually test whether the EOSD was scaled.
Basically, it only checked whether vo_gl had the scaled-osd suboption
set.
