selftests: mptcp: connect: also cover checksum

commit fdf0f60a2bb02ba581d9e71d583e69dd0714a521 upstream.

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.

[ Conflict in Makefile, in the context, because userspace_pm.sh test
  has been introduced later, in commit 3ddabc433670 ("selftests: mptcp:
  validate userspace PM tests by default"), which is not in this
  version. ]
