Set default culture to en-US

So that the resource manager doesn't try to load a non-existent
satellite assembly (and thus throw).

The culture `en-US` is the default `CurrentCulture` on all platforms I
tested, specifically not `en`.

Note that there is a problem with the FullCLR build where some other
assembly is still attempting to reference `Logging.resources` instead of
`System.Management.Automation.Logging.resources`.
