Update time zone data files to tzdata release 2013i.

DST law changes in Jordan; historical changes in Cuba.

Also, remove the zones Asia/Riyadh87, Asia/Riyadh88, and Asia/Riyadh89.
Per the upstream announcement:
    The files solar87, solar88, and solar89 are no longer distributed.
    They were a negative experiment -- that is, a demonstration that
    tz data can represent solar time only with some difficulty and error.
    Their presence in the distribution caused confusion, as Riyadh
    civil time was generally not solar time in those years.
