Control viv.json creation

[weslambert]

When running the Linux version of Capa (may apply to all versions), a viv.json file is copied to the running user's home directory ($HOME/.viv/viv.json ). Is there a way to control where this file is copied, or to disable its creation on the host?

huh, i never noticed this. looks like a configuration file used to tweak vivisect's default behavior.

it doesn't look like vivisect provides a way to configure this behavior: https://github.com/vivisect/vivisect/blob/da818a84e68876e625dca07550457df029a2b4ad/vivisect/__init__.py#L78
while there might be a way to reach in an patch the workspace to avoid saving the config, this sounds pretty brittle. let me open an issue against vivisect and see if they'll provide a mechanism for this.

this is fixed upstream.

we have some outstanding work to do to use the official vivisect available on pypi, so i'll likely bundle together these fixes.

closed in 09da1d1 with the bump to viv 0.1.0
