patch

The attached patch should fix this.  We have the same problem if stdout or
stderr
is closed, since cmp(1) calls caph_limit_{stdout,stderr}().  Also, if all three
streams are closed, the caph_limit_stderr() call will fail because
STDERR_FILENO isn't a valid fd.

These problems aren't specific to cmp(1), they'll affect anything using these
helpers.  I think the fcntl() calls in the patch should be lifted into the
corresponding Capsicum helpers.
