Vfs::Dir_file_system: do not use Vfs_handle for opening directories as files

Browse Source 
The Dir_file_system uses static cast to convert handles from the
application to a plugin local type. For this reason, only the local
handle type may be returned from 'opendir' or 'open'. This fixes the
unexpected behavior when opening directories as files.

Fix #2533
