perf tools: Add machine_pid and vcpu to perf_sample
When parsing a sample with a sample ID, copy machine_pid and vcpu from
perf_sample_id to perf_sample.
Note, machine_pid will be zero when unused, so only a non-zero value
represents a guest machine. vcpu should be ignored if machine_pid is zero.
Note also, machine_pid is used with events that have come from injecting a
guest perf.data file, however guest events recorded on the host (i.e. using
perf kvm) have the (QEMU) hypervisor process pid to identify them - refer
machines__find_for_cpumode().
