hsc2hs copies #define/#undef directives to generated .hs file when cross-compiling

See summary. This causes a cross-compilation of ghc to fail while building GHC/Stack.hsc from libraries/base, because base.cabal no longer specifies extensions: CPP as of [dfb52c3d5/base].

    Don't emit #define/#undef in generated .hs files
    
    ... just like they aren't emitted in the ordinary case; see outTokenHs
    in C.hs.
    
    Closes #8393.
