libteam: switch to python3

The original fix for team_basic_test.py only change the interpreter
to python3, but still some error as below:
 # ./run-ptest
 File "/usr/lib64/libteam/ptest/./team_basic_test.py", line 35
 print "Usage: team_basic_test.py [OPTION...]"
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?

 # ./run-ptest
 RUN #1
 # "ip link add testteamx type team"
 # "teamnl testteamx getoption mode"
 # "ip link del testteamx"
 # "modprobe -r team_mode_loadbalance team_mode_roundrobin team_mode_activebackup team_mode_broadcast team"
 Traceback (most recent call last):
  File "/usr/lib64/libteam/ptest/./team_basic_test.py", line 206, in <module>
    main()
  File "/usr/lib64/libteam/ptest/./team_basic_test.py", line 203, in main
    btest.run()
  File "/usr/lib64/libteam/ptest/./team_basic_test.py", line 180, in run
    self._run_one_loop(i + 1)
  File "/usr/lib64/libteam/ptest/./team_basic_test.py", line 173, in _run_one_loop
    self._run_one_mode(mode_name)
  File "/usr/lib64/libteam/ptest/./team_basic_test.py", line 101, in _run_one_mode
    cmd_exec("teamnl %s getoption mode" % team_name, "*NOMODE*")
  File "/usr/lib64/libteam/ptest/./team_basic_test.py", line 80, in cmd_exec
    raise CmdExecUnexpectedOutputException(output, expected_output)
 __main__.CmdExecUnexpectedOutputException: Command execution output unexpected: "b'*NOMODE*'" != "*NOMODE*"

 So rework team_basic_test.py to fix the above issue.
