[PATCH mptcp-next v7 8/9] selftests: mptcp: connect: cover zerocopy mode

From: Geliang Tang <[email protected]>

Add a new test script mptcp_connect_zerocopy.sh to run the mptcp_connect
selftest with the zerocopy I/O mode. This ensures the MSG_ZEROCOPY path
is exercised in the regular test suite.

The script follows the same pattern as the existing mmap, sendfile, and
splice test wrappers, invoking mptcp_connect.sh with the -m zerocopy
option.
