bug#9498: "Not an in-range integer,..." when using Synergy

[Chong Yidong]

Thanks.

The culprit seems to be Paul Eggert's 2011-08-26 change (Bug#9196) to
lisp_data_to_selection_data, which forces numeric values to be saved to
the X selection data member with a maximum allowed value of X_LONG_MAX
== 2147483647.  This breaks for timestamps like 3345671365.

The patch below probably fixes the error for this specific bug, but I
will leave it up to Paul to figure out if it's the right fix.

Paul, please review your change.  Thanks.
