sysutils/vagrant: use sysutils/bundler17

[mmoll]

Summary

The bundler update to 1.10 does not play well with vagrant, see PR 200614. While building in poudriere, I saw missing plist entries. The maintainer didn't react the last days to the PR and to another mail from me and as it's just a small fix, I hope that's OK without his approval.

Proposed commit message:

sysutils/vagrant: use sysutils/bundler17

while here, sort and fix plist
