Don't require a local sshd for the local TCP state dtrace test
This change is similar to the one done in r286171 for tst.ipv4localtcp.ksh. This not only reduces the requirements on the system used for testing but results also in a graceful teardown of the TCP connection. Reviewed by: gnn@ Sponsored by: Netflix, Inc.
