journald: introduce new "systemd-journal" group and make it own the journal files
Previously all journal files were owned by "adm". In order to allow specific users to read the journal files without granting it access to the full "adm" powers, introduce a new specific group for this. "systemd-journal" has to be created by the packaging scripts manually at installation time. It's a good idea to assign a static UID/GID to this group, since /var/log/journal might be shared across machines via NFS. This commit also grants read access to the journal files by default to members of the "wheel" and "adm" groups via file system ACLs, since these "almost-root" groups should be able to see what's going on on the system. These ACLs are created by "make install". Packagers probably need to duplicate this logic in their postinst scripts. This also adds documentation how to grant access to the journal to additional users or groups via fs ACLs.
