Silence python -m wheel {pack, unpack} at unvendoring stage

[ryanking13]

After #116, I noticed that there are verbose logs printed at the very end step of recipe build:

It is because python -m wheel {pack, unpack} prints these logs to stdout. So, I added a verbose parameter to silence these outputs when we don't want them.
