[PATCH] tools/perf: Add includes for detected configs in Makefile.perf

Makefile.perf uses "CONFIG_*" checks in the code. Example the config
for libtraceevent is used to set PYTHON_EXT_SRCS

	ifeq ($(CONFIG_LIBTRACEEVENT),y)
	  PYTHON_EXT_SRCS := $(shell grep -v ^\# util/python-ext-sources)
	else
	  PYTHON_EXT_SRCS := $(shell grep -v '^\#\|util/trace-event.c' util/python-ext-sources)
	endif

But this is not picking the value for CONFIG_LIBTRACEEVENT that is
set using the settings in Makefile.config. Include the file
".config-detected" so that make will use the system detected
configuration in the CONFIG checks. This will fix isues that
could arise when other "CONFIG_*" checks are added to Makefile.perf
in future as well.
