app/testpmd: hide --bitrate-stats in help if disabled

[ upstream commit e96491cb91fd048a79e848d713d65d45f0dde915 ]

Like other #ifdef options, bitrate-stats should not be printed
in help if not configured.

Also reordered latencystats help string to group it with bitrate-stats.

Fixes: e25e6c7 ("app/testpmd: add --bitrate-stats option")
