[golang/go] cmd/link: set darwin LC_BUILD_VERSION SDK version field higher by default

### ROOT CAUSE The issue arises because the Go compiler sets an older SDK version in the LC_BUILD_VERSION header during internal linking. This causes libraries to invoke compatibility routines meant for older SDKs, leading to discrepancies compared to external linking, which uses newer versions. Apple's clarification confirmed that using a higher SDK version in internal linking doesn't affect compatibility with older macOS versions. ### CODE FIX To resolve the issue, update the SDK version used in internal linking to match external linking's newer version. This adjustment ensures consistency and prevents compatibility issues.

This change sets the SDK version higher by default, aligning internal linking with external linking and resolving compatibility issues.
