* [PATCH 2/2] lei: avoid close(STD{IN,OUT,ERR}) in oneshot mode

This seems to fix the occasional "make check-run" failures I've
been chasing.

Some parts of our code assumes we can close($lei->{1})
and similar, which causes IO::Handle::autoflush to behave
badly when STDOUT is the "select"-ed FH of the Perl process.
Since oneshot mode is (hopefully) the uncommon case, we'll
just accept the cost of extra FDs and minimize differences
between lei in oneshot vs daemon mode.

It turns out the oneshot mode of lei was causing problems and
propagating them to other tests.  1/2 helped me finally get to
the bottom of it and fix it in 2/2.
