Subject: [PATCH 2/5] perf tools: Move callchain_param to util object in to fix python test

In following commit we changed the location of callchains data:
  b016b5ba554b perf tools: Move callchain config from record_opts to callchain_param

Now all callchains stuff stays in callchain_param struct,
which adds its dependency for evsel.c object and breaks
python perf.so usage (unresolved callchain_param).

Moving callchain_param into callchain.c and adding it into
python-ext-sources unleash just another dependency hell,
so I ended up adding callchain_param into util.c for now.
