doubled-word typos in timezone/europe and southamerica

[Jim Meyering]

This fixes three instances of doubled words
in the "europe" and "southamerica" files.
I noticed these in glibc's files, which may well
be out of date.  FYI, I ran this command to spot candidates:

  git ls-files |xargs perl -0777 -n \
    -e 'while (/\b(then?|[iao]n|i[fst]|but|f?or|at|and|[dt]o)\s+\1\b/gims)' \
    -e '{$n=($` =~ tr/\n/\n/ + 1); ($v=$&)=~s/\n/\\n/g;' \
    -e 'print "$ARGV:$n:$v\n"}'

--------------------------
Remove doubled words in comments, e.g., s/do do/do/, s/the the/the/
