system: File systems depend on their corresponding device mappings.
Fixes a regression introduced in commit 0adfe95. * gnu/system.scm (other-file-system-services)[requirements]: Remove. [add-dependencies]: New procedure. Use it. * gnu/system/file-systems.scm (<file-system>)[dependencies]: Update comment. * gnu/services/base.scm (mapped-device->dmd-service-name, dependency->dmd-service-name): New procedures. (file-system-service-type): Use it.
