mk: fix output directory name when compiling with custom kernel header dir

  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.

You are changing the alignment :)

This change is only for the "make" system.
How does it work for meson?

The issue doesn't seem to be happening when using meson build system,
kernel modules are compiled into correct directory.
