Pex fails to extract archive members with UTF-8 names on linux with non-UTF-8 default encoding.

[jsirois]

The details of the discovery are documented over here: pantsbuild/pants#3823

The underlying condition is to be ~expected given the sys docs here: https://docs.python.org/2/library/sys.html#sys.getfilesystemencoding.

Fix this problem for zips and also tarballs if the problem is present.

This problem is not present for tarballs. I verified using the OP from pantsbuild/pants#3823 under LANG=en_US.ISO-8859-1 which has a Cyrillic test data file name in both the zip and tarball sdists:

target = tempfile.mkdtemp()
with tarfile.open("CherryPy-7.1.0.tar.gz") as tf:
    tf.extractall(target)
