eal: fix C++11 compilation

When compiling C++11-code or above (--std=c++11), the build fails with
lots of

  rte_eth_ctrl.h:517:3: note: in expansion of macro RTE_ALIGN
    (RTE_ALIGN(RTE_ETH_FLOW_MAX, UINT32_BIT)/UINT32_BIT)
    ^

When reading the GCC info pages, I get the feeling that __typeof__ is
a better choice, and that indeed works when including the headers in
C++ files (--std=c++11).
