[PATCH 1/1] Add support for minimal systems without 'tree'

[Trevor Vaughan]

In minimal environments, `tree` may not exist. This
patch adds support for using `find` instead.

The `tests/setup.sh` file was also modified to detect and fail if the
`git` and `diff` commands were not present on the system running tests.
