Give some hints to Perl on the use of UTF-8 for output

* scripts/dpkg-genchanges.pl, scripts/dpkg-gencontrol.pl,
scripts/dpkg-source.pl: Hint Perl into using UTF-8 for output
on *.dsc, *.changes and DEBIAN/control files. Updated some open() calls
for more consistency and added binmode() calls for filehandles that
handle only binary data.
