lei up --all: avoid double-close on shared STDOUT

This is merely to avoid perl setting errors internally which
were not user visible.  The double-close wasn't a problem in
practice since we open a new file hanlde for the mbox or
mbox.gz anyways, so the new t/lei-up.t test case shows no
regressions nor fixes.
