orphaning dblatex to allow a new maintainer

[Alex Lancaster]

Hi there,

As I don't use this package much anymore,  I am dropping back to co-maintainership
and orphaning dblatex to let somebody else be the primary owner, see:

https://admin.fedoraproject.org/pkgdb/acls/name/dblatex

It's a pretty minimal package in terms of maintenance, mainly
requires keeping on top of TeX BuildRequires etc which don't change
too often
