perf config: Honour $PERF_CONFIG env var to specify alternate .perfconfig
We had this comment in Documentation/perf_counter/config.c, i.e. since when we got this from the git sources, but never really did that getenv("PERF_CONFIG"), do it now as I need to disable whatever ~/.perfconfig root has so that tests parsing tool output are done for the expected default output or that we specify an alternate config file that when read will make the tools produce expected output.
