options: remove --subfont-autoscale (changes default font scale)

The code for this option attempted to emulate the old as-documented
behavior. It wasn't very good at it, and now that the old OSD code has
been removed, it's entirely pointless.

This removes the factor 1.7 with which --subfont-text-scale was
multiplied.
