fs-util: add new CHASE_WARN flag to chase_symlinks()
This flag can be used to make chase_symlinks() emit a warning when it
encounters an error.
Such flag can be useful for generating a comprehensive and detailed warning
since chase_symlinks() can generate a warning with a full context.
For now only warnings for unsafe transitions are produced.
