Fix sandbox crash during reload of logging configuration
Allow calls to dup() which was introduced in commit a22fbab986.
From a security perspective, I don't think this should impact the
security of the sandbox significantly. As far as I can tell, there
is nothing an adversary can do with a duplicated FD that can't be
done with the original.
