dpkg-buildpackage: Call gpg with --utf8-strings

(signfile): Call gpg with --utf8-strings since otherwise the key
lookup fails with non-ASCII UTF8-encoded names. Since Debian
changelogs should be UTF8 encoded, this is probably the more sane
default.

+	will probably break if one uses a non-UTF8 locale
+	and tries to give a uid on the commandline that
+	contains non-ASCII chars. I think we can live with
+	that.
