Ticket 50564 - Fix rust libraries by default and improve docker

Bug Description: Rust libraries were not installed properly
due to quirks of autotools and cargo. Containers as a result
couldn't start in some cases.

Fix Description: Fix this by building rust
libraries as static libs and linking them into existing .so files
instead.

-# Both cargo and autotools are really opinionated. You can't generate the correct

-# convince automake to use the outputs we *do* have. So instead, we manually
