test(otlp-http): add span flags to trace exporter test expectations

Add SPAN_FLAGS_CONTEXT_HAS_IS_REMOTE_MASK flag with sampled bit (1) to all span assertions in trace_exporter_test.rb to align test expectations with actual span flag behavior.

- Add flags field to 6 span test assertions
- Set flags to SPAN_FLAGS_CONTEXT_HAS_IS_REMOTE_MASK | 1 (sampled)
- Ensures test expectations match the span flags set during export
