Fix yocto-check-layer syntax error

�� Syntax Error Fix:
- Remove invalid --no-auto-dependencies flag
- The flag doesn't exist in yocto-check-layer script
- Restore working yocto-check-layer command syntax
- Ensure distro layer CI validation runs without syntax errors

This fixes the syntax error that was causing the
yocto-check-layer command to fail in distro layer CI.
