Bug#866723: vtk6: FTBFS due to texlive-math-extra no longer existing

[Bas Couwenberg]

Source: vtk6
Version: 6.3.0+dfsg1-5
Severity: serious
Tags: patch
Justification: makes the package in question unusable or mostly so

Dear Maintainer,

While preparing the transition to GDAL 2.2.1, your package failed to
build due to unsatisfied build dependencies:

 Depends: texlive-math-extra which is a virtual package and is not
 provided by any available package

The recent revisions of texlive-extra no longer provide this binary
package.

Dropping the build dependency was sufficient to build vtk6 successfully
again.

Please apply the attached patch to drop the dependency.

Kind Regards,

Bas
