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.
