Debian patch fixing the warning

On newer perls (all current Fedora releases including 15 are affected), use of this module results in a deprecation warning. It's visible in the test suite:

$ make test
PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/*.t
t/byteswap.t ... ok
defined(%hash) is deprecated at /builddir/build/BUILD/Unicode-String-2.09/blib/lib/Unicode/CharName.pm line 80.
        (Maybe you should just omit the defined()?)
t/charname.t ... ok
t/encoding.t ... ok
t/op.t ......... ok
t/ord.t ........ ok
t/stringify.t .. ok
All tests successful.
