vzmigrate: make -vvv add -vv to rsync

Previously, specifying -v 3 times was used to add -v to ssh/scp.
Now with verbosity of 3 we add yet another -v to rsync, so it will show
some more information about which files to consider etc.

To have ssh/scp print debug output, specify -v four times (or -vv
two times etc.)
