kernel_dir option in meson build is equivalent to RTE_KERNELDIR in make
system, for cross-compilation case, users would specify it as local
kernel src dir like
/<user local dir>/target-arm_glibc/linux-arm/linux-4.19.81/
Current meson build would fail to compile kernel module if user specify
kernel_dir as above, this patch fixes this issue.
