When /bin/sh points to bash vs. dash, two classpath files get generated
different with different content.

The attached patch fixes this in debian/rules by using printf instead of
echo, as echo implementations vary in the handling of "\n" in different

According to my local tests, applying this patch should make
gradle-jotlin-dsl build reproducibly on tests.reproducible-builds.org!

Thanks for maintaining gradle-kotlin-dsl!
