work around ghc segfault

hSetEncoding of a closed handle segfaults.
https://ghc.haskell.org/trac/ghc/ticket/7161

8484c0c1976b2daa4be674b09f6f54c15c746aa6 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

Thanks to Mesar Hameed for assistance related to reproducing this bug.
