video: Allow console output to be silenced
When using expo we want to be able to control the information on the
display and avoid other messages (such as USB scanning) appearing.
Add a 'quiet' flag for the console, to help with this.
The test is a little messy since stdio is still using the original
vidconsole create on start-up. So take care to use the same.
