Allow the caller of the zpool-create.sh script to override the default path where file vdevs are created. This allows for greated flexibilty when scripting. Additionally, update the default path from /tmp/ to /var/tmp/ because these days /tmp/ is likely a ramdisk. Even though these files are sparse they may grow large in which case they should be backed by a physical device.
