Fix legacy facts

[joneswac]

Puppet version 8 deprecates legacy facts: https://www.puppet.com/docs/puppet/7/core_facts.html#legacy-facts

There are a variety of these through this module that need to be updated.

Example:
with legacy facts

    default: {
      case $::operatingsystem {
        default: {
          fail("Unsupported platform: ${::osfamily}/${::operatingsystem}")
        }
      }
    }

fixed to modern facts

default: {
      case $facts['os']['name'] {
        default: {
          fail("Unsupported platform: ${facts['os']['family']}/${facts['os']['name']}")
        }
      }
    }

Apologies, my system installed a very old version of this module.
