vmon: add %P fmt specifier for getpid()
vmon already handles SIGUSR1 for producing png snapshots on
demand, adding a fmt specifier for substituting the vmon PID
makes for convenient scripting of triggering such snapshots.
i.e:
$ vmon -- /bin/bash -c 'for((i = 0; i < 10; i++)); do kill -USR1 %P; sleep 1s; done'
Would produce ten png snapshots of the charts on 1-second
intervals.
