Now that we require Python 3.4 or later, Python code creating temporary directories can use tempfile.TemporaryDirectory in "with" to have the directory deleted automatically instead of needing to use try/finally to handle removing a directory created with tempfile.mkdtemp. This patch does so in conform/glibcconform.py. Tested for x86_64. * conform/glibcconform.py: Do not import shutil. (list_exported_functions): Use tempfile.TemporaryDirectory instead of mkdtemp.
