[tz] Set up correct name to Zone Europe/Kyiv

[Alexey Furashev]

Hello All,

In  source file https://github.com/eggert/tz/blob/master/europe please
change city name to correspondent standards ISO 3166-2:UA and UNGEGN.

We have to write bug reports to software developers, because time zone
entry names are incorrect.  Incorrect name of time zone entries can't
be used for our practical needs.
