file-systems: Spawn a REPL only when interaction is possible.
Fixes <https://bugs.gnu.org/23697>.
Reported by Jan Nieuwenhuizen <janneke@gnu.org>.
* gnu/build/file-systems.scm (check-file-system): Call 'start-repl' only
if current-input-port passes 'isatty?'.
* gnu/services/shepherd.scm (shepherd-configuration-file): After
'for-each' expression, call 'redirect-port'.
* gnu/tests/base.scm (run-basic-test)["stdin is /dev/null"]: New test.
