localedata: Use the name North Macedonia.

The name "the former Yugoslav Republic of Macedonia" is no longer in use
since the signing of the Prespa Agreement [1][2].  This resolved the
country's naming dispute with Greece and changed the name to "North
Macedonia".

The name field of this locale/iso-3166.def is not used, so this does not
affect binaries.
