[PATCH 1/2] perf record: Fix sample cgroup & namespace tracking

[Namhyung Kim <namhyung@kernel.org>]

The recent change in perf_tool constification broke the cgroup and/or
namespace tracking by resetting tool fields.  It should set the values
after perf_tool__init().

Fixes: cecb1cf154b30 ("perf record: Use perf_tool__init()")
