Update Windows images to RS5 (#550)

Update the Dockerfiles to point to the RS5 nanoserver base image.

This change also makes some minor tweaks to the Windows installer script in preparation for turning on UDS/RS5:
- If an archive folder is passed rather than a ZIP file, create the iotedge directory first before trying to copy to it. Not sure why this wasn't failing before, maybe the build job that uses this feature is pre-creating the folder.
- When creating the parent directory for the UNIX domain socket files, pipe to null so that the `Get-SecurityDaemon` function _only_ returns the intended boolean value.
- During uninstall, if the event log component directory doesn't exist (e.g., because it was already deleted), ensure `Remove-SecurityDaemonResources` still returns `$true` so that the user sees a satisfying completion message ("Successfully uninstalled IoT Edge.") at the end.
- Print some more errors when the -Verbose switch is specified.
- During uninstall, remove the `IOTEDGE_HOST` system environment variable.
- Use PowerShell's `Get-Acl` and `Set-Acl` instead of .NET Core's `[System.IO.Directory]::GetAccessControl` and `[System.IO.Directory]::SetAccessControl` (which Windows IoT Core doesn't have).
- Set up the service to automatically restart when it fails.
