Use bundled rust deps

Use bundled deps as we don't ship the exact right versions for all the
required rust libraries. This makes it possible to e.g. ship librsvg2
security updates for F28 whereas previously we were version locked
because F28 didn't have the correct rust library versions.

If you're updating the package in the future and notice that we have
all the deps available in Fedora, feel free to change it back to non
bundled deps.
