Qt5 don't re-register system fonts
System fonts are already registered in the QFontDatabase. And
addApplicationFont seems to be really expensive especially when
registering large fonts like the Noto CJK fonts, which increases
load time by 4 seconds per font.
This skips all font + style combinations already known in the DB.
Since addApplicationFont already relies on fontconfig on Unix/X11
this should be fine.
