pkg/vcs: add repo OptPrecious and OptDontSandbox options

The pkg/vcs code assumed that we fully manage the repo
within an autonomous program. In particular it tried
to repair any errors by dropping and re-creating the repo.
This does not work well for command-line tools that work
with a user-provided repo. Add OptPrecious for such uses.

Update #2171
