Backport #7911: 特定の条件の時に、File.fnmatchに渡すpatternがUS-ASCII、pathがUTF-8だとInvalid sequenceでエラーが出る

=begin

coding: utf-8

File.fnmatch('a'.encode('US-ASCII'), 'あ', File::FNM_CASEFOLD)

というコードを実行した際に、

test-fnmatch.rb:2:in fnmatch': invalid byte sequence in US-ASCII (ArgumentError) from test-fnmatch.rb:2:in '

というエラーが発生します。UTF-8文字列である'あ'を、'a'と同じUS-ASCIIだとしてcase insenstiveなマッチのためにupcaseを試みているのがエラー原因と思われます。

添付のパッチで動作するようになることを確認しました。
