tests: Add '--no-huge' param to dpif-dpdk tests

This parameter prevents configuration of huge pages, which is
unnecessary for the dpif-dpdk unit tests. This change results in a
significant reduction in the time it takes for tests to execute, as
seen below:

    $ time sudo tests/test-dpif-dpdk -c 1 -n 4 -- port-add
    ...
    APP: Found OVDK01_Control_Alloc_Ring

    real    0m16.730s
    user    0m8.841s
    sys     0m7.768s

    $ time sudo tests/test-dpif-dpdk -c 1 -n 4 --no-huge -- port-add
    ...
    APP: Found OVDK01_Control_Alloc_Ring

    real    0m0.066s
    user    0m0.012s
    sys     0m0.029s
