Revert 243802 "PPAPI: Add new PPB_FileRef.MakeDirectory to suppo..."

This breaks examples of NaCl SDK.

> PPAPI: Add new PPB_FileRef.MakeDirectory to support exclusive operation
> 
> Current PPB_FileRef.MakeDirectory returns PP_OK if a directory exists on
> the given path. This makes it difficult to create POSIX compatible API on
> top of PPAPI.
> 
> This change introduces new PPB_FileRef.MakeDirectory as dev channel API.
> That makes a new directory according to the given PP_MakeDirectoryFlags
> values. The flags provide exclusive operation option. If exclusive flag
> is specified and a directory exists on the given path, the function fails
> and returns PP_ERROR_FILEEXISTS.
