font-patcher: Fix patching woff files

[why]
After we added the possibility to process font archives (.ttc) we lost
the ability to process woff and woff2 fonts.

It seems woff(2) files show no font names in fontforge, see
fontforge/fontforge#1964

[how]
Open woff(2) files differently.

Fixes: #1647 (further down)
