[PATCH 1/6] test: Update fs_helper to support passing in the image

[Simon Glass]

This function is useful for other scripts, so add a parameter to specify
the image name, if desired.

Also add a flag to quieten the output of some of the tools, since in
many cases we only want to see warnings / errors.
