libnet-vampire: add attributes and classes from the replicated schema to the bootstrap schema (bug #8680)

Replicated schema might have attributes and auxilary classes  on some
critical classes (ie.  top, user, computer ) that are not in the bootstrap
schema. Without those new attributes and classes, bootstrap schema is
unable to translate those critical classes in the schema constructed
from the replicated data. Without thoses classes new schema is useless
and can't be indexed properly.

In order to overcome this problem, we put all new attributes and classes
definitions into the bootstrap schema so that foundations classes can be
translated.
