Upgrade to trixie, set MAKEFLAGS, PGUSER

*   Upgrade to `trixie-slim`
*   Set `PGUSER` to `postgres` in the `Dockerfile`, removing the need
    for users to remember to do it.
*   Set `MAKEFLAGS="-j $(nprocs)"` in `pgxn-build-test` and pass `-j
    $(nprocs)` in `pgrx-build-test` to shorten build runtimes
