Sorry, can't see what the problem is.
You can create a folder into kobopatch src (kobopatch_4.11.12019/src/delete_files) and there put the files with the content you need.
Perhaps something like:

Spoiler:

#!/bin/sh

rm usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/Amasis*
# rm /usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/Avenir*
rm usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/Caecilia*
# rm usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/georgia*
rm usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/GillSans*
rm usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/KBJ*
rm usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/KoboNickel*
rm usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/Malabar*
rm usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/OpenDyslexic*

rm /etc/udev/rules.d/delete_fonts.rules
rm /root/delete_fonts.sh

Note I've commented Avenir and Georgia because they are system fonts. Perhaps you want to replace them with yours.
Then add the correspondant lines into files section of kobopatch.yaml:

Spoiler:

files:
  src/delete_files/delete_fonts.rules: etc/udev/rules.d/delete_fonts.rules
  src/delete_files/delete_fonts.sh: root/delete_fonts.sh

Good luck.
