Remove redundant CompareString from llgo:skip directive

[xgopilot]

Summary

• Removed redundant CompareString from the llgo:skip init CompareString directive in runtime/internal/lib/internal/bytealg/bytealg.go

Details

The CompareString in the directive was redundant because:

1. The overlay mechanism automatically handles symbol skipping when an overlay package defines a symbol
2. There's no need to explicitly declare llgo:skip CompareString
3. The explicit skip directive was misleading, suggesting special handling was needed when the overlay mechanism handles it automatically

Changes

• Changed // llgo:skip init CompareString to // llgo:skip init in runtime/internal/lib/internal/bytealg/bytealg.go:26

Fixes #1351
