Zip::FileSystem::ZipFsDir#glob triggers non-existing Zip::FileSystem::ZipFileNameMapper#glob method

[AlexWayfer]

Code:

require 'zip'
require 'zip/filesystem'

Zip::File.open('archive.zip') do |zip_file|
  zip_file.dir.glob('flags/**/*')
end

Output:

NoMethodError: undefined method `glob' for #<Zip::FileSystem::ZipFileNameMapper:0x00005654bd818c98>
from /home/alex/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/gems/rubyzip-1.2.1/lib/zip/filesystem.rb:475:in `glob'

Hi @AlexWayfer, I've had a go at fixing this. Does PR #363 do what you expect?

Hello. Sorry, I don't remember. But I think yes.
