bug#15262: 24.3.50; desktop does not save buffer-display-time

[Sam Steingold <sds@gnu.org>]

desktop saves the buffers, but not their buffer-display-time.
i.e., when Emacs is started and desktop loads all the old buffers,
their buffer-display-time is set to the Emacs start time.
this leads to ancient buffers not being cleaned up by clean-buffer-list.
