Bug#1120872: ruby-gnuplot: please make the build reproducible

[Chris Lamb]

Source: ruby-gnuplot
Version: 2.6.2-4
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
ruby-gnuplot could not be built reproducibly.

This is because it ships a different binary package depending on
whether the testsuite is run or not. Specifically, sin_wave.gif is
generated in the tests only (not in the build); a patch is attached
that will delete this file and ensure it is not shipped in the
binary package.
