hadrian: fix bindist makefile for wasm32-wasi target

This patch fixes one incoherent place between bindist makefile and
hadrian logic: I forgot to include wasi/wasm32 in
OsSupportsGHCi/ArchSupportsGHCi as well. And this results in incorrect
settings file generated after installing the bindist, and "Use
interpreter"/"Have interpreter" fields incorrectly have "NO" values
where they should be "YES" like --info output of in-tree version.
