perf kvm: Make perf kvm diff support --guestmount.
In manpage of perf-kvm, --guestmount is supported by diff command, but it does not work well.
This patch change the extend the checking in buildid-diff from guestkallsyms or guestmodules to perf_guest. Then this checking can cover the all cases perf kvm is used for.
