commit 5de5f8184530fd7e0e88514ae35cb2e9305910c1

file-systems: Have the emergency REPL output to /dev/console.
This fixes a bug whereby all emergency REPL output would go to /dev/klog
and thus, each line would be prefixed by "[12324.432] shepherd[1]: ".
* gnu/build/file-systems.scm (check-file-system): Wrap 'start-repl' call
in 'with-output-to-file'.
