Mark several 389-ds-base issues as no-dsa

Those are almost all minor issues. Marking those as no-dsa is surely not
the optimal solution, but 389-ds-base has outside Red Hat worlds
defintivel less imapct as OpenLDAP is almost the prefered solution.

Furthermore those 389-ds-base bugs are quite weird cases to cover and
backporting single patches for 389-ds-base have high potential for
regressions.
