hw/9pfs/9p-synth: added directory for readdir test 



This will provide the following virtual files by the 9pfs
synth driver:

  - /ReadDirDir/ReadDirFile99
  - /ReadDirDir/ReadDirFile98
  ...
  - /ReadDirDir/ReadDirFile1
  - /ReadDirDir/ReadDirFile0

This virtual directory and its virtual 100 files will be
used by the upcoming 9pfs readdir tests.
