work around ghc segfault
hSetEncoding of a closed handle segfaults.
https://ghc.haskell.org/trac/ghc/ticket/7161
3b9d9a267b7c9247d36d9b622e1b836724ca5fb0 introduced the crash.
In particular, stdin may get closed (by eg, getContents) and then trying
to set its encoding will crash. We didn't need to adjust stdin's
encoding anyway, but only stderr, to work around
