firmware-ath9k-htc is missing in Debian/testing due to
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=997767. Its fix is
stuck in the open-ath9k-htc-firmware package in Debian's NEW queue since
5 months (see https://ftp-master.debian.org/new.html).
At least for the time being, let's drop it from GRMLBASE, to get fresh
Debian/testing based daily ISO builds again.
