Samuele Pedroni f83b1f1560 many: progress bars should use the overridable stdouts (#12047)
making progress bars should take a stdout io.Writer

ToolingStore should carry an overridable stdout

make sure in image, preseed and cmd/snap code the overridable
top-level Stdout is passed along to make progress bars
