    fd: Initialize more export_fd_buf fields in kern_proc_cwd_out()
    
    In particular, we need to initialize efbuf->flags, since
    export_vnode_to_sb() loads that field.  This was mostly harmless since
    the flag only determines whether the output kinfo_file is packed, and
    KERN_PROC_CWD only ever emits a single kinfo_file anyway.
