::kernel is not defined

[craiggenner]

When the ::kernel fact is not defined then Package[wget] is not set and so define wget::fetch => exec { "wget-${name}": also fails.

Additionally Package[wget] is only set when $manage_package is set to true.

Not sure what a fix would look like, I wonder if some extra logic to not depend on the the Package[wget] if the ::kernel fact isn't true or $manage_package is false. I also wonder what happens to the exec if the kernel is set to FreeBSD.

Happy to provide a fix by the way of a pull request once I have some guidance as to which way a fix should go.

change if $var_that_might_exist { ... } to if defined('$var_that_might_exist') { ... }
