Modify dev/Vagrantfile to handle chef licensing

This adds support for accepting chef licensing only if the version of
chef-server is 13+.  Without this, any attempt to use the
`dev/Vagrantfile` to install an older version of chef-server would
result in failures due to the lack of `--chef-license` flag.
