app-misc/pax-utils: backport python-3.7 support, bug #671522

Fix by Oleksandr Natalenko:

lddtree.py: use errno properly

os.errno interface is removed [1], thus should not be used. In fact, it
is not used in other places of lddtree.py, so fix this one too, because
it breaks --copy-to-tree on systems with Python 3.7.
