charts: Wall=??s if proc_stat->start is > boottime
Since libvmon samples the sys_wants before proc_wants, it's
entirely possible the proc_stat->start will be later than
sys_stat->boottime by the time a given process gets sampled.
Simply treat this analogous to being unable to sample the start,
either of which will only leave the Wall as ??s in the highly
ephemeral short-lived process scenario. In the > boottime case,
the next sample for the same process would have start <= boottime
