Various changes to integrate LMDB source files

Browse Source 
- revert previous changes from configure.ac script in order to re-use
  the existing logic, as well as the gitlab ci flag which check build
  with two combinations.

- Conditionally build LMDB source code based on HAVE_LMDB. So if
  --without-lmdb is used, HAVE_LMDB won't be set and LMDB source code
  will be compiled and included in libisc. This enable code using LMDB
  to link no matter LMDB is OS-provided or not.

- Regarding the LMDB headers, and in order to make future LMDB update
  easier, all original OpenLDAP code is wrapped under
  lib/isc/openldap-lmdb including the headers. This avoid extra
  changes (putting aside liscence header) to mdb.c to find out its
  headers. The counter-part is the relative inclusion of this header
  from isc/lmdb.h header, but it's probably a good idea to not make
  this header public anyway.

- update LMDB license to add BIND9 SPDX headers but mentioning LMDB
  lisence
