Introducing following bits to the the perf_event_attr struct:
- exclude_callchain_kernel to filter out kernel callchain
from the sample dump
- exclude_callchain_user to filter out user callchain
from the sample dump
We need to be able to disable standard user callchain dump when we use
the dwarf cfi callchain mode, because frame pointer based user
callchains are useless in this mode.
Implementing also exclude_callchain_kernel to have complete set of
options.
