file-systems: Preserve UUID types when serializing.
Reported by Roel Janssen <roel@gnu.org>
at <https://lists.gnu.org/archive/html/help-guix/2017-09/msg00094.html>.
* gnu/system/file-systems.scm (file-system->spec): When DEVICE is a
UUID, serialize it in a way that preserves its type.
(spec->file-system): Adjust accordingly.
* gnu/build/file-systems.scm (canonicalize-device-spec): Add case for
when SPEC is 'uuid?'.
