[dpdk-stable] [PATCH v3] mk: fix output directory name when compiling with custom kernel header dir

[Herakliusz Lipiec]

When building dpdk with differnt kernel headers by specifying
RTE_KERNELDIR igb_uio is compiled to directory with a name of the
version of kernel thats running on the system instead of the one that
dpdk is actually compiled against. Fixed by replacing hardcoded value
with value from RTE_KERNELDIR.
