travis: fix mk-build-deps call by providing changelog file

mk-build-deps started using the changelog file to get the version number, but a
bug prevents it from falling back correctly to 1.0 if no changelog is
present. This has been fixed upstream in
https://salsa.debian.org/debian/devscripts/commit/4b15abd4f0cfe4accbf28f24546891867344a73c,
but we can just ship the changelog file until that fix lands.
