- Remove /etc/susehelp.d and subdirectories, susehelp is gone
- Remove /etc/tmpdirs.d, support was removed 2011 and migrated
to tmpfiles.d
- Remove /var/adm/perl-modules (support was removed with 11.4)

- Get ride of the last non-root group. /run/lock is created by
systemd, not filesystem, so remove it from here.

- Change ownership of /etc/ppp, group dialout has meanwhile another
meaning and there are no setgid dialout binaries who could need
that.
