perf evsel: Probe for precise_ip with simple attr
Currently we probe for precise_ip with user specified perf_event_attr,
which might fail because of unsupported kernel features, which would get
disabled during the open time anyway.
Switching the probe to take place on simple hw cycles, so the following
record sets proper precise_ip:
# perf record -e cycles:P ls
# perf evlist -v
cycles:P: size: 112, ... precise_ip: 3, ...
