[RFC 1/1] tools/virtiofsd: create temporary directory in /tmp

[Jens Freimann <jfreimann@redhat.com>]

mkdtemp() will try to create a current directory in the working
directory of the process. In this case it's trying to create it in /.
This is a problem when the process doesn't have write access there.

This patch changes the template string and prepends "/tmp" which is
typically writable.
