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.
