fix: exclude WIT-dependent test targets from CI to prevent transitive builds

Resolved CI failures where excluded calculator_component was still being built
through transitive dependencies from test targets under //test/go/...

Excluded specific test targets:
- test_calculator_component_provides_info
- test_calculator_component_valid_wasm
- test_calculator_exports_verification

These tests depend on //examples/go_component:calculator_component which requires
WIT dependencies unavailable in current TinyGo toolchain (documented in Issue #82).
