Subject: Fix here document with EOF

#### Before this patch:

  ```
  $ bin/mruby -e 'p <<EOS
1
EOS'
  -e:4:0: can't find heredoc delimiter "EOS" anywhere before EOF
  -e:4:0: syntax error, unexpected $end, expecting tHEREDOC_END or tHD_STRING_PART or tHD_STRING_MID
  ```

#### After this patch (same as Ruby):

  ```
  $ bin/mruby -e 'p <<EOS
1
EOS'
  "1\n"
  ```
