When invoked from drw_fontset_getwidth(), `render` wont be active, so
yeah this will get rid of the infinite recursion as well. And
ellipsis_width is only relevant when rendering, so it makes sense to do
it this way.

In fact, I think just reducing the condition to `if (render)` and
reverting ellipsis_width to be automatic variable again would work as
well. But since ellipsis_width won't change, makes sense to make it
static and calculate it only once.

Currently it's used only in 2 locations, so don't think it should be
hard for someone to change it if they wish.

Attached the amended patches.
