[PATCH 1/4] perf report: Do not extend sample type of bpf-output event

[Namhyung Kim]

Currently evsel__new_idx() sets more sample_type bits when it finds a
BPF-output event.  But it should honor what's recorded in the perf
data file rather than blindly sets the bits.  Otherwise it could lead
to a parse error when it recorded with a modified sample_type.
