During a build of extension module within `pip wheel` the source directory is recursively copied in a temporary directory. See https://github.com/pypa/pip/issues/7555 When the temporary directory is inside the source directory (for example by setting `TMPDIR=$PWD/tmp`) this caused an infinite recursion that ended in: [Errno 36] File name too long We prevent that buy never copying the target to the target in _copy_source_tree. Fixes https://github.com/pypa/pip/issues/7872

Prevent an infinite recursion with ``pip wheel`` when ``$TMPDIR`` is within the source directory.
