system: Allow the root file system to be named by UUID.
* gnu/build/file-systems.scm (canonicalize-device-spec)[canonical-title]: Use 'string->uuid' to check whether SPEC is a UUID. When SPEC is a string and CANONICAL-TITLE is 'uuid, call 'string->uuid'. * gnu/system.scm (operating-system-grub.cfg): Add 'root-device' variable and use it for the "--root=" argument.
