Revert "Initial DPDK support"

This reverts commit ce5e82e319.

MicroStack cannot currently install due to a missing ovs-related
library. This is possibly due to recent changes in spacraft, or
possibly due to the workarounds for those changes. Regardless, it
appears that backing out the DPDK changes gets us back to a state
where we can install.
