fix driver:local in prefixing volumes

If we have a docker-file with root level volumes and we do a kompose up
using that docker-file, libcompose will add an additional _ followed by
the current directory name. Since kubernetes doesn't allow _ in the
objects created so kompose up will fail to deploy it. As a solution we
replace _ to - and we can then deploy it successfully.
