fix: error --enable-aci requires --enable-dynacl

[dev-zhandos]

There is an error error: --enable-aci requires --enable-dynacl during installation of iRedMail with the LDAP backend on FreeBSD. I think we need to enable dynacl for OpenLDAP due to conditions in the configuration file. More details can be found in the official git repository of OpenLDAP

486 if test $ol_enable_aci = yes ; then
487     if test $ol_enable_dynacl = no ; then
488         AC_MSG_ERROR([--enable-aci requires --enable-dynacl])
489     fi
490 elif test $ol_enable_aci = mod ; then
491     AC_MSG_ERROR([ACI build as dynamic module not supported (yet)])
492 fi
