xci: bifrost: Fix unbound variable error

If we are not in a virtual environment, then VIRTUAL_ENV is going
to be unset and we will fail with the following error:

./scripts/bifrost-provision.sh: line 105: VIRTUAL_ENV: unbound variable

As such, we need to provide a default value if that variable is unset.
We also fix a typo in the _sudo variable.
