    libpager: Do not flush in-core pages on offer
    
    pager_offer_page () is documented to may ignore the offered page if
    the kernel already has a copy in core (indeed, that's what Mach does).
    
    However the current behavior is the inverse of that: it asks the kernel
    to flush (i.e. drop) its in-core copy, and replace it with the offered
    one. Fix this by not doing that, and calling memory_object_data_supply ()
    directly.
