Add d/source/options to ignore .gitreview

dpkg-buildpackage and debuild source builds fail due to the
.gitreview file in the root directory, which is not present in the
upstream tarball, and thus causes a build failure due to the
unexpected diff.
Add a source/options file to extend the default file ignore list to
fix the problem.
