Currently gVisor only outputs the flags field in fdinfo, which causes the Python library psutil to fail with IndexError when parsing fdinfo, as they expect pos to be the first line. Add the typical base fields pos and mnt_id. - pos: via Seek(ctx, 0, SEEK_CUR), defaults to 0 for non-seekable fds - mnt_id: from file.Mount().ID Signed-off-by: Tan Yifeng <yiftan@tencent.com>
