trace-cmd: upgraded package to upstream

Upgraded dev-util/trace-cmd to version 2.8.3 on amd64

This tool is used as a wrapper tool around ftrace, trace events, etc.
It's not actually included in any images yet, but it's useful as an
optional debugging extension for hostap's tests (especially since the
WiFi subystem has a number of useful trace points in the kernel).

BUG=chromium:1013471
TEST=hostap hwsim tests, with '--trace' option
