Cleanup cfg blocks

Remove obsolete references to target_env = wasi, target_os = nacl,
target_os = osx, and a typo'd target_os = fushsia that didn't compile
when fixed.

 - target_env = wasi is dead: https://github.com/rust-lang/rust/pull/60117
 - target_os = nacl is dead: https://github.com/rust-lang/rust/pull/45041
 - target_os = osx is dead, but I can't find a link.
