Without that, all mptcp_connect*.sh subtests have the same name, e.g.

  mptcp_connect: ping tests  ## from mptcp_connect.sh
  mptcp_connect: ping tests  ## from mptcp_connect_checksum.sh
  mptcp_connect: ping tests  ## from mptcp_connect_mmap.sh
  mptcp_connect: ping tests  ## from mptcp_connect_sendfile.sh

In such case, the CI will only see one subtest, not 4 different ones.

To fix that, MPTCP_LIB_KSFT_TEST env var can simply be set.
