perf_counter: Set the CONFIG_PERF_COUNTERS default to y if CONFIG_PROFILING=y
If user has already enabled profiling support in the kernel
(for oprofile, old-style profiling of ftrace) then offer up
perfcounters with a y default in interactive kconfig sessions.
Still keep it off by default otherwise.
