[Buildroot] [PATCH v4] trace-cmd : new package

[Pierre Floury <p.floury@gmail.com>]

This commit adds a new package for the trace-cmd tool.
This tool is a command line front end of ftrace.
It collects traces on your target.
You can analyse these traces on the target or on the host via
the gui "kernel shark".
