Bug#1032014: setupcon: do not copy security attribute

[Christian Göttsche <cgzones@googlemail.com>]

Package: console-setup
Version: 1.217
User: selinux-devel@lists.alioth.debian.org
Usertags: selinux
Tags: patch

When copying files into the temporary working directory do not copy
the security context but use the default one for the target path.
Otherwise, e.g. when using SELinux, the context might not be allowed
on the destination filesystem and the process needs elevated access to
the original context.
