selftests: mptcp: connect: also cover checksum

The checksum mode has been added a while ago, but it is only validated
when manually launching mptcp_connect.sh with "-C".

The different CIs were then not validating these MPTCP Connect tests
with checksum enabled. To make sure they do, add a new test program
executing mptcp_connect.sh with the checksum mode.

Fixes: 94d66ba1d8e4 ("selftests: mptcp: enable checksum in mptcp_connect.sh")
