Lintian tag information: invalid-field-for-derivative (type: error)

Description (from lintian-explain-tags)

The specified field in debian/control does not match the required format
for this Debian derivative.

Derivative distributions of Debian may enforce additional restrictions on
such fields for many reasons including ensuring that:

- Debian maintainers are not contacted for forked or packages that
are otherwise modified by the derivative.
- The original maintainer is still credited for their work (eg. in a
XSBC-Original-Maintainer field).
- References to revision control systems (eg. Vcs-Git) are
pointing to the correct, updated location.
- Fields that become misleading in the context of a derivative are
removed.
