[dash-launcher] Load libraries from multiple packages

`library_loader` now supports multiple library directories.

`dash-launcher` now supplies libraries from two sources:
* `/pkg/lib` of the explored component
* `/pkg/lib` from the launcher namespace

This ensures that binaries packaged with the launcher
can run successfully.

Test: fx test library_loader
