Fix crash on <fn=1>x</fn> when no additional fonts are specified
This fixes the following crash that happens with the default xmobar
configuration (using HOME=/ makes xmobar ignore ~/.xmobarrc):
$ echo "<fn=1>x</fn>" | HOME=/ xmobar
xmobar: Prelude.!!: index too large
Commit 3e9e1cb9d300 ("Fix crashes/busy looping happening via index")
meant to fix this but apparently it only fixed indexing of fontlist, not
voffs, so the crash was still there.
Fixes: https://github.com/jaor/xmobar/issues/504
