vos: Show after effects in dryrun mode

vos: Show after effects in dryrun mode

The dryrun mode of operation for 'vos syncvldb' and 'vos syncserv'
does not currently show the "status after" portion of its output, so
they don't really show what the commands will do. Change them so
"status after" is shown for -dryrun when sync'ing servers or
partitions, and count changes towards the count at the end.
