perf evlist: Rename __group method to __set_leader

Just like was done for parse_events__set_leader.

Also we need to have the list_entry set_leader method in evlist.c so that we
don't grow another dep in the python binding:

 # ~acme/git/linux/tools/perf/python/twatch.py
 Traceback (most recent call last):
   File "/home/acme/git/linux/tools/perf/python/twatch.py", line 16, in <module>
     import perf
 ImportError: /home/acme/git/build/perf/python/perf.so: undefined symbol: parse_events__set_leader

And also remove a pr_debug from evsel.c so that we avoid this one too:

 # ~acme/git/linux/tools/perf/python/twatch.py
 Traceback (most recent call last):
   File "/home/acme/git/linux/tools/perf/python/twatch.py", line 16, in <module>
     import perf
 ImportError: /home/acme/git/build/perf/python/perf.so: undefined symbol: eprintf
