font-patcher: Fix crash when no xavgwidth data available

Browse source 
[why]
When we did not collect xavgwidth data for some font and want to tweak
it the font-patcher crashes.

[how]
Check if we have a number before accessing it in the array.

[note]
This happens when font_patcher.patch() has not been called.
