This fixes a fairly large tempfile leak. Vagrant uses a template renderer to write network configuration files locally to disk. Then, that temporarily file is uploaded to the remote host and moved into place. Since Vagrant is such a short-lived process, GC never came along and cleaned up those tempfiles, resulting in many temporary files being created through regular Vagrant usage. The Util::Tempfile class uses a block to ensure the temporary file is deleted when the block finishes. This API required small tweaks to the usage, but provides more safety to ensure the files are deleted.
