qemu-binfmt-service-type is defined in (gnu services 
virtualization).

I just use grep, but found out while researching this mail that we 
provide a nice ‘guix system search’ command to find out which 
module provides a service

 λ guix system search qemu
 name: qemu-binfmt
 location: gnu/services/virtualization.scm:745:2
 extends: file-systems shepherd-root guix
 shepherdnames: qemu-binfmt
 description: This service supports transparent emulation of 
 binaries compiled for other architectures using QEMU and the 
 `binfmt_misc' functionality of the kernel Linux.

Adding packages to your system configuration won't (and can't and 
mustn't) affect services in this way.
