Extend compatibility header system to support librte_cmdline.

pthread.h has to include windows.h, which exposes struct in_addr, etc.
conflicting with compatibility headers. WIN32_LEAN_AND_MEAN macro
is required to disable this behavior. Use rte_windows.h to define
WIN32_LEAN_AND_MEAN for pthread library.
