Show blocker parents for non slot-conflict pkgs.

Show parents for packages involved in blocker conflicts but not
directly involved in slot conflicts, since this information may be
helpful for troubleshooting blocker conflicts. This information had
been hidded when there were unrelated simultaneous slot conflicts,
since commit 77b651300731ec007cd535a83b8ee9a898602783.
