LICENSE file not packaged with individual crates

[dminor]

In our Cargo.toml files we have a license-file with a relative path back to the root LICENSE file. This means that LICENSE is not actually packaged with the individual crates, which breaks tooling that expects to be able read the LICENSE file, like the vendor_rust.py script used to vendor crates into Firefox.

Assuming we can't use license in Cargo.toml to OR together the different licenses we're using, I think that we'll have to include a copy of the LICENSE file with each component that we package as a separate crate.

It looks like this is a problem with cargo vendor not with the packaging. I'll leave this open in case there is something we need to do in our Cargo.toml file to make cargo vendor happy.
