Bring back Lomiri-specific notification hints

As discussed in [1], Lomiri has a custom logic in notification timeout
and require the custom hint for timeout to work correctly. Restore the
hints from commit 0a88a8d7 ("Remove osd-notify remnants and use native
notification timeout"), while keeping the standard timeout in place.
Lomiri will ignore standard timeout, while other DE's will ignore the
extra hint.
