package/sentry-cli: re-add package
This reverts commit d19077677fc71fc8c8cd73945606f773d907a99a, but the
package now uses the cargo-package infrastructure with its vendoring
mechanism, which allows us to avoid the problems that caused the
package to be removed in d19077677fc71fc8c8cd73945606f773d907a99a.
