tests/example/: Explcitly compute namespace 

The namespace of e.g. "tests/examples/awful/mouse/coords.lua" is "_awful_mouse".
This is purely based on the path of the file.

Previously, this was computed while recursively scanning the directory tree.
This commit instead moves this to an extra function that handles this task.
