fix compilation error when there is no default printer defined

Use puppetlabs/xinetd for cups-lpd

xinetd module defaults to “root” for the group when none is specified.
Cups docs recommends using “sys”

Hands off responsibility for defining and managing the xinetd service
to puppetlabs/xinetd module.  Avoids service resource duplicate errors
for the xinetd service.

Use of xinetd::service in config causes Service[‘xinetd’] to be defined
and receive notifications of changes in the service file, so it should
not need to be included in cups::service.

Add package install options

Make default printer an exec configured w/ a param. Thanks @lamawithonel 

This creates a `hiera_hash()` lookup for the `printer_defaults` type,
similar to what is already done for the `printer` type.

This adds an empty hash to the `hiera_hash()` printer lookup to prevent
an error in case Hiera cannot find any printers.

This removes the `default_printer` type and provider and makes it an
exec instead, fed by a parameter to the init class.  Using an exec like
this ensure the attribute remains singleton.

This makes several changes to clean up the Puppet code.  With this it
mostly pass puppet-lint using the default settings, inherits from params
notwithstanding.  It also tabularizes key/value pair lists, removes some
blank lines and makes variable scope explicit.
