Reorganize Git interface scripts

Move the Git interface scripts from git-interface/ to aurweb/git/. Use
setuptools to automatically create wrappers which can be installed using
`python3 setup.py install`. Update the configuration files, the test
suite as well as the INSTALL and README files to reflect these changes.
