vzmigrate: fix logging

Commit ea203fb5bc changed echo to printf because echo -e is not
portable. Unfortunately it did it in a bad way:
 (1) no newline character
 (2) bad number of arguments to printf

Revert it and go back to standard echo. But do not use -e now,
fixing a few statements than relied on it by changing \t to spaces.
Use $* and put it inside the doubple quotas to save these spaces.
