chore: remove no-longer-necessary build.rs for Rust bindings

The build.rs is a long-since-unnecessary customization since we adopted the
object_store crate and no longer manage storage ourselves. This change also
allows us to purge the glibc-version build dependency which makes the build a
teensy bit faster too.
