ci(release/freebsd): build the native bindist only (no JS cross)

The FreeBSD self-hosted runner has no JS toolchain (llc/opt/emscripten), so it
cannot build the javascript-unknown-ghcjs cross target. Drop both the JS
bindist and haskell-toolchain.tar.gz (which depends on
stage3-javascript-unknown-ghcjs) from the FreeBSD build; ship only the native
ghc/cabal/tests bindists.
