After ERP5's 992c0ff13e8b5ac78cca4e7195de383418291892 we need to explicitly add this bt5 dependancy.

This patch is similar to
nexedi/erp5@530e8b4e
(nexedi/erp5!1445) and amends Wendelin test
driver to run tests on a real storage and spawn WCFS as needed.

Running tests on a real storage instead of in-RAM MappingStorage is
required in wendelin.core 2 case, because WCFS and Zope need to access the
same ZODB, and if Zope keeps data inside in-RAM MappingStorage, there
is no easy way for WCFS to access it. In such a case tests are failing as e.g.

-> Fix it by using a real storage for tests via --load/--save hack, and via
--with_wendelin_core requesting to spawn WCFS when built with wendelin.core 2.
