When ServerSshHost = 'local' the server-binary stage skips scp/ssh and
does an in-place Copy-Item + chmod + Move-Item on the local filesystem.
Pre-flight pgrep also runs locally. Allows running the deploy script on
the server itself (glados in our case) without setting up ssh-to-self.
Other deploy modes (remote scp/ssh) unchanged.
