perf session: Embed the host machine data on perf_session
We have just one host on a given session, and that is the most common setup right now, so embed a ->host_machine struct machine instance directly in the perf_session class, check if we're looking for it before going to the rb_tree. This also fixes a problem found when we try to process old perf.data files where we didn't have MMAP events for the kernel and modules and thus don't create the kernel maps, do it in event__preprocess_sample if it wasn't already.
