remotefilelog: rework workaround for sshpeer deadlocks
The wrapping of `sshpeer.cleanup` silently broke when `cleanup` was
renamed to `_cleanup`, a couple of years ago.
I don't know what `orig.im_self` is, but regardless, the intention of
the wrapping seems pretty clear: close stderr before
sshpeer._cleanuppipes blocks on it. So do that.
