Hmm, I already gave it a lower priority than the default. At least, I 
gave it priority number "10", which is called a low priority package by 
the Nixpkgs manual.

linux-nonfree is apparently some Debian meta-package and can indeed be 
commented out. The others do add firmware...

The problem seems to be that the Debian packages also include firmware 
that is already shipped with the kernel. The default nixos kernel 
configuration includes that firmware, and thus causes a collision. I 
guess that the best solution would be if the firmware shipped with the 
kernel would be prioritized over the firmware in the linux-nonfree 
package. However, setting the priority is apparently not enough?

(I cannot reproduce the problem, because my kernel config says 'N' to 
the inclusion of firmware so I don't have this collision)
