perf callchain: Move callchain_param to util object in to fix python test

In following commit we changed the location of callchains data:

  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.
