[PATCH 7/8] perf tools: Create config.detected into OUTPUT directory

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Aaro Koskinen <aaro.koskinen@nokia.com>

Create config.detected into OUTPUT directory instead of source
directory.

This fixes parallel builds that share the same source directory.
