Disable zlib in LLVM on Haiku

PR rust-lang#72696 enabled the option LLVM_ENABLE_ZLIB for the LLVM builds. Like NetBSD and aarch64-apple-darwin (see PR rust-lang#75500), the LLVM build system not explicitly linking to libz on these platforms cause issues. For Haiku, this meant the runtime loader complaining about undefined symbols..
