Dpdk in VM: Increase num_mbufs

Since switching to rxq ratio 1:1,
the previous value was not enough for 4c vhost tests.

+ Set the 1:1 rxq ratio also for DPDK (outside vhost) tests.
 - Still not sure why those tests were not failing.
+ Set the 1:1 rxq ratio also for VPP container tests.

Ticket: CSIT-1783
