services: Add dconf-service-type.
This allows the dconf profile directive "system-db:" to look up profiles by
name from under /etc/dconf/db/.
* gnu/services/xorg.scm (dconf-keyfile, dconf-profile): New procedures.
(dconf-profiles?): New predicate.
(dconf-configuration): New procedure.
(dconf-profile->profile-file): Likewise.
(dconf-profile->db-keyfile): Likewise.
(dconf-profile->db-keyfile-dir): Likewise.
(dconf-profile->db): Likewise.
(dconf-profile->files): Likewise.
(dconf-service-type): New service type.
