ci: Reduce optional libraries in DPDK.

Since DPDK v23.11, it is possible to select more easily which optional
library is enabled.

OVS needs the vhost library (and its dependencies).
The net/tap DPDK driver needs the gso library.
Other optional library can be disabled.

This reduces the cache entry for DPDK from ~7MB to ~4MB.
