Disable host-arch feature of cranelift-codegen

This ensures that cg_clif can be built for targets that aren't natively
supported by Cranelift. It will not be possible to compile for the host
in this case, but cross-compilation will still be possible.

We won't distribute cg_clif as rustup component for any targets that
aren't natively supported by Cranelift, but will still build it if
codegen-backends lists "cranelift".
