dpdk: Disable building FreeBSD kernel modules

Disable building the FreeBSD kernel modules, while these are required
to run, this dpdk step will fails inside the vpp build.

If the build succeeded this step would try to install the kernel modules
as root in the vpp build which also isn't desirable. For packaging the
kernel modules should be provided in a seperate package rather than
through the vpp build process.

Type: improvement
