gnu: Don't abuse check-btrfs-file-system to scan.

Browse source 
It was never guaranteed to be run for non-root file systems.  It was for
root file systems only due to a bug now fixed.

* gnu/build/file-systems.scm (check-btrfs-file-system): Don't invoke
‘btrfs device scan’ here.
* gnu/system/linux-initrd.scm (raw-initrd): Do so here if any btrfs file
systems are present.
