openldap: use recommended backend mdb

The mdb backend to slapd(8) is the recommended primary backend for a
normal slapd database. Add PACKAGECONFIG 'mdb' to enable it and build
mdb as SLAPD_STATIC_BACKENDS.

This fixes the errors while starting slapd:

  $systemctl start slapd
  Job for slapd.service failed because the control process exited \
  with error code. See "systemctl status slapd.service" and \
  "journalctl -xe" for details.

  $ systemctl status slapd
  ...
  /etc/openldap/slapd.conf: line 53: <database> failed init (bdb)
  Unrecognized database type (bdb)
  slapd.service: Control process exited, code=exited status=1
  ...
