[dpdk-dev] [PATCH v2] app/test-pmd: fix meson build failed when used latency stats lib

[SteveX Yang]

meson build cannot find the header rte_latencystats.h when build DPDK
first time or never installed DPDK lib after build via meson/ninja.

Because the corresponding header directory isn't included after enabled
RTE_LIBRTE_LATENCY_STATS flag.

Add the lib 'latencystats' to deps of meson.build of test-pmd, the
corresponding header files will be included automatically.

Fixes: 62d3216d6194 ("app/testpmd: add latency statistics calculation")
