Add debug symbols to packages (Azure#587)

Currently, we provide symbol packages for all the distros we build, with the exception of Mariner (disabled due to a rust issue, then never reverted). However, the packages don't contain our symbols because we instruct rustc to build the release configuration, which doesn't emit debug information by default.

This change updates Cargo.toml to enable full debug information in release builds. It also reverts the config that was supressing symbol packages in Mariner. The deb/rpm packaging tools already strip symbols from release binaries and generate symbol packages, so no further changes are needed.
