system: Add the 'system?' field for user groups.
Suggested by Mark H. Weaver. * gnu/system/shadow.scm (<user-group>)[system?]: New field. (%base-groups): Introduce 'system-group' macro, and use it. * gnu/system.scm (user-group->gexp): Pass the 'system?' field. * guix/build/activation.scm (add-group): Add #:system? and honor it. (activate-users+groups): Handle the 'system?' field. * gnu/system/file-systems.scm (%tty-gid): Choose an ID below 1000. * doc/guix.texi (User Accounts): Document the 'system?' field.
