Fix rust publishing step (rapidsai#984)

In rapidsai#816 we started to vendor
rapids_config.cmake - but this broke the symlinks that rust/java use to
build.

Fix the symlinks to point to the new location, and add a precommit hook
to check that symlinks are valid to prevent this from happening in the
future
