pylibfdt: add requirements.txt for setuptools

Add a requirements.txt file to the pylibfdt script directory to specify
setuptools as a dependency. This follows the pattern of each tool in
U-Boot having its own requirements.txt file. The version is set to
78.1.1 to avoid conflict with the same in tools/patman/requirements.txt.
