Multiple match tags do not work with --use-v1-config

Reported by @sanemat

Previously, following config worked:

<source>
  type forward
  port 24224
</source>

<match raw.** foo.**>
  type stdout
</match>

But, with --use-v1-config, we get errors like:

/home/sonots/src/github.com/fluent/fluentd/lib/fluent/config/basic_parser.rb:87:in `parse_error!': expected '>' at fluent2.conf line 6,14 (Fluent::ConfigParseError)
  5:
  6: <match raw.** foo.**>

     --------------^
  7:   type stdout
        from /home/game/src/github.com/fluent/fluentd/lib/fluent/config/v1_parser.rb:87:in `parse_element'
        from /home/game/src/github.com/fluent/fluentd/lib/fluent/config/v1_parser.rb:41:in `parse!'
        from /home/game/src/github.com/fluent/fluentd/lib/fluent/config/v1_parser.rb:31:in `parse'
