Bug#927544: Updating the libdebian-installer Uploaders list

[Tobias Frost <tobi@debian.org>]

Source: libdebian-installer
Version: 0.112 0.117 0.118
Severity: minor
User: mia@qa.debian.org
Usertags: mia-teammaint

Christian Perrier <bubulle@debian.org> has retired, so can't work on
the libdebian-installer package anymore (at least with this address).

We are tracking their status in the MIA team and would like to ask you
to remove them from the Uploaders list of the package so we can close
that part of the file.

(If the person is listed as Maintainer, what we are asking is to please
step in as a new maintainer.)

Thanks.
