[PROF-11306] Package libdatadog v16.0.1 for Ruby

**What does this PR do?**

This PR includes the changes documented in the "Releasing a new version
to rubygems.org" part of the README:
https://github.com/datadog/libdatadog/tree/main/ruby#releasing-a-new-version-to-rubygemsorg

**Motivation:**

Enable Ruby to use libdatadog v16.0.1. Of particular interest, this
includes improvements to crashtracking and the managed string table
needed by DataDog/dd-trace-rb#4331 .

**Additional Notes:**

N/A

**How to test the change?**

I've tested this release locally using the changes in
DataDog/dd-trace-rb#4353 .

As a reminder, new libdatadog releases don't get automatically picked up
by dd-trace-rb, so the PR that bumps the Ruby profiler will also test
this release against all supported Ruby versions.
