Older version tc command (iprout2 5.3) shows actions in multiple lines,
not a single line. Then the following unexpected MP_FAIL selftest output
occurs:

 file received by server has inverted byte at 169
 ./mptcp_join.sh: line 1277: [: [{"total acts":1},{"actions":[{"order":0 pedit ,"control_action":{"type":"pipe"}keys 1

                                       sum[ ok ] - csum  [ ok ]
                                       ftx[ ok ] - failrx[ ok ]

                                       itx[ ok ] - infirx[ ok ]
                                       ftx[ ok ] - failrx[ ok ] invert

This patch adds a 'grep' before 'sed' to fix this.

Here's a typo in commit log, it should be 'iproute2 5.3'. Please help me
to fix this when merging this patch.

Thanks,
