Hm. I now realize smoke.t is relying on xvfb getting pulled in via the
build dependencies, and using it only when it's available. This approach
does not work for syntax.t and use.t, where xvfb-run is almost always
not going to be available.

The test dependencies come from /usr/share/autodep8/support/perl/generate,
so that would need an update. I wonder if that's overkill for a handful
of packages. Thoughts?

Not sure if configurability is necessary for these tests. #895190 is
easily solvable with existing infrastructure (smoke-env), and I'd
like to avoid making this stuff even more complex. So I'm inclined
to start small here (if at all).
