Profiling Guide Requires Updates

[Trott]

In light of nodejs/node#3032, there is some stuff in the simple profiling guide that can be simplified. Maybe @matthewloring can indicate what needs to change? It might just be the part about making sure to use the same version of tick-processor as came with the source and how to fire up the tick processor? Not sure anything else...

@Trott Thank you for noticing this. I'll submit a PR with updates now that the tick processor is bundled with the node binary.

The page is still referring to the v8 profiling tools in the source code (which I believe are no longer included).

Good catch. Actually, the integration of the --prof-process flag into the LTS branch means we should remove all mention of scripts from the guide.
