[TT-11925] Reset plugin compiler build env to match gateway build env (#6234)

## **User description**
Gateway uses bullseye for the build, while plugin compiler used
bookworm. This resets the plugin compiler to use bullseye, as the build
environment has to match for plugin compatibility.

This also removes unnecessary packages.
