fix: exclude additional *_host targets with Rust triple mismatch issues

Add exclusions for host variants that have the same Rust target triple
mismatch pattern:
- //examples/basic:hello_component_wasm_lib_release_host (Linux)
- //examples/wasm_signing:example_component_wasm_lib_release_host (macOS)

These targets expect host platform triples but find wasm32-wasip2
dependencies. Part of broader cross-compilation configuration issue
tracked in GitHub issue #16.
