[Foo2zjs-maintainer] Bug#449497: Bug#449497: foo2zjs: application depends on non-free firmware

[Michael Gilbert]

the problem with external dependencies is that functionality can be
broken due to circumstances outside of your control.  vis a vis, the
getweb stuff is currently broken (in unstable as well as stable!)
because the upstream author randomly decided to modify his directory
naming scheme.  this is why debian policy required that there are no
dependencies on packages outside of main.
