[PATCH] lei_to_mail: don't close STDOUT unless it is a mbox* output

[Eric Wong <e@80x24.org>]

We only care about error checking when stdout is an mbox output
pointed to a pathname.  This is noticeable with `lei up' with
multiple non-mbox* destinations.  We'll also ensure throwing
exceptions to trigger lei->x_it from lei->do_env results in the
epoll/kqueue watch being discarded, otherwise commands may never
terminate (leading to stuck tests)
