Updates build scripts for improved environment handling

Enhances testbench workflow by explicitly setting environment variables,
ensuring consistent paths for tools and libraries during builds.

Refines default workspace path in build-alsa-tools script to use `$HOME`,
increasing flexibility for user environments.
