vagrant: add netbsd (needs more work)

there's a problem with the shell:
- either it is no login shell, then e.g. PKG_PATH is not set (sh)
- or it is not found (no bash here)
- or it is not compatible enough (csh)

depending on what shell is configured, one or the other vagrant mode / feature
does not work.
