vzdump: allow plugins to set guest resume time

Browse Source 
This refactors things a bit to avoid having the same two lines in 3
places and allows the plugin to set the "guest was resumed" time
stamp at the point it really was resumed, not only once the backup
completed (see #503). Further, if a plugin prints it's own
"resumed/running after X seconds" message, it can unset the vmstop
time and thus avoid printing the message twice.

related to a fix for #503
