services: qemu-binfmt: Add requirement.

* gnu/services/virtualization.scm (qemu-binfmt-shepherd-services)
[requirement]: Add file-system-/gnu/store.

qemu-binfmt service write references to the store to
/proc/sys/fs/binfmt_misc/qemu-[architecture] files, therefore
/gnu/store needs to be mounted during the lifetime of the service
instance. If /gnu/store does not remain mounted, the issues
discussed by nigko and Rutherther on IRC are arisen:
