Leo Yan ebf39d29b9 perf hist: Add 'kvm_info' field in histograms entry

__hists__add_entry() creates a temporary entry and compare it with
existed histograms entries, if any existed entry equals to the
temporary entry it skips to allocation to avoid duplication.

The problem for support KVM event in histograms is it doesn't contain
any info to identify KVM event and can be used for comparison entries.

This patch adds 'kvm_info' field in the histograms entry which contains
the KVM event's key, this identifier will be used for comparison
histograms entries in later change.
