Jie Zhou 3c60274c09 test: skip unsupported tests on Windows 
Skip tests which are not yet supported for Windows:
- The libraries that tests depend on are not enabled on Windows yet
- The tests can compile but with issue still under investigation
    * test_func_reentrancy:
      Windows EAL has no protection against repeated calls.
    * test_lcores:
      Execution enters an infinite loops, requires investigation.
    * test_rcu_qsbr_perf:
      Execution hangs on Windows, requires investigation.
