Unorphaning wbxml2

[Laurent Rineau <laurent rineau__fedora_extras normalesup org>]

I am taking the ownership of *wbxml2*, which is a retired package (because its 
maintainer could not sign the Fedora CLA due to its company policy).

wbxml2 is a requirement of libsyncml, which I would like to get into Fedora 
Extras as well.

Actually, I failed to detect that wbxml2 was orphaned. I thought it was not in 
Fedora Extras at all. I have submitted a Review Request, which is already 
accepted. See:
  https://bugzilla.redhat.com/217180

I will merge the previous changelog into my spec file before submitting it.
