[rfc][patch] perf,tools: Remove test_attr_* muck from perf.h

[Peter Zijlstra]

Hi,

I occasionally build the odd program against raw perf and use perf.h for
this.

Now I find that no longer works because of:

52502bf201a85 ("perf tests: Add framework for automated perf_event_attr tests")

So revert the hunk touching on perf.h.

Also, it seems to be for snake shit only, and snakes stink, except on a
plane :-)
