[RFC PATCH 07/13] ez: use portable uid/gid accessors in write_to_tar

[Adrian Neftali Sanchez <lutgaru@gmail.com>]

os.getuid and os.getgid are POSIX-only; calling them directly raises
AttributeError on Windows.  Use getattr with a lambda returning 0 so tar
entries are created with a harmless numeric uid/gid on platforms that do
not have POSIX user identifiers.
