Fix install-options

I tryed
````
    package { "ghostscript":
      ensure => installed,
      install_options => [
                          '--with-x11'
                          ],
    }
````
it is not install_options install binary.
because, monky_pach(boxen-install) from S3.

I want have install_options binary.
so, have install_options case, use "brew install".
