Fixes for publishing rust package to crates.io (#207)

Some minor fixes that are required to publish our rust bindings to crates.io:

 * using relative paths in the cuvs-sys cmake files didn't work, get around this by symlinking required files instead
 * Need to specify an actual version for cuvs-sys and ndarray-rand packages in the rust/cuvs/Cargo.toml file
