Make vdpm be quiet

[IngwiePhoenix]

I am setting up Topgrade on my systems and two of them have the VitaSDK (and others) installed - using topgrade to keep them up to date is really neat. Unfortunately, vdpm is super noisy. :)

Would it be possible to make it silent - or at least only output "Installing somepackage" instead of the whole curl/untar outputs?
