Description

Using _dl_find_object is more efficient (less lock contention). But when libunwind is built against musl, it doesn't use this path at runtime.

Also pin the image sha in CI for building purposes so that in the futures the changes in unmerged updates are not automatically propagated once we update the image in datadog/images.
