Make test appears to be broken in a few places when the backends are built as
modules.

1. In the run script: When back-bdb, back-hdb, back-ldbm, and back-monitor are
built as modules, AC_BDB, AC_HDB, AC_LDBM,and AC_MONITOR are set to "mod", not
"yes". This causes the if statements beginning at line 40 to fail, because they
are looking for "yes". The net result is that the run script exits with the
message "Not configured with a suitable database backend".

2. In test000-rootdse: slapd doesn't start because the slapd.conf file that is
used in that test is missing the module load statement for the backend module.

Make test with modules was working in HEAD as of the 11/25 HEAD snapsot we
took.
