Replace FROM scratch with ubuntu:24.04 in Dockerfiles

[vgpopov]

Purpose

Scratch base images lack basic tooling and debugging capabilities, making container troubleshooting difficult. Replace with pinned Ubuntu 24.04 LTS for a consistent, debuggable base.

Changes

• Replace FROM scratch with FROM ubuntu:24.04 in lib/other/biowasm-tools/Dockerfile (multi-stage final stage)
• Replace FROM scratch with FROM ubuntu:24.04 in tests/package-builder/30.software-pkg/Dockerfile
• Replace FROM scratch with FROM ubuntu:24.04 in tools/package-builder/src/__test__/Dockerfile

Tests

No new tests — config-only Dockerfile change, covered by existing Docker build CI.
