back-mdb tries to read entry databases prior to initialisation, which leeds to segmatation fault

slapo-dds was misbehaving, fixed now in master. Overlays that hook the db_open entry point are required to check for (slapMode & SLAP_TOOL_MODE) and exit as a no-op in that case. slapo-dds was not doing this. It caused slapcat to crash as well.

This problem was triggered by using the dds-max_dynamocObjects setting, which makes slapo-dds fire off a search at startup to find entries to expire/delete. Of course this operation fails in slapcat anyway, since the database is opened read-only.
