    xwayland: Use CurrentTime on all XConvertSelection calls
    
    The call fetching the targets mistakenly used the timestamp meant
    to back up the TIMESTAMP atom (hence, it's the timestamp at which
    the selection is *owned* by the compositor, on behalf of a wayland
    client).
    
    This timestamp is actually only updated when the compositor gets
    to own the selection, so it's a randomly late timestamp to retrieve
    the TARGETS atom content, which certain clients might end up
    ignoring.
