explicitly build deprecated classes

The recently @Deprecated classes are not used any more by Caja, so
they are no longer compiled automatically via transitive dependency,
so they never end up in the caja jar file, which breaks external
packages that still use those classes.

This CL adds a rule to explicitly build the deprecated classes.
I'm keeping this short and simple because I don't expect us to need
any more such classes, and I'm hoping that the external references
will be deleted soon anyway.
