config: enable packet prefetching with Meson

Browse Source 
With Make build system, RTE_PMD_PACKET_PREFETCH was enabled
by default. It got lost when transitioning to Meson build
system.

In order to avoid performance changes, this patch enables
packet prefetching in rte_config.h.

Fixes: 9314afb68a53 ("drivers: add infrastructure for meson build")
