Use long options in the cloud-init disk_setup.sh template

Convert any short options with long alternatives. There is specifically
an interaction with `mkfs` where the underlying filesystem handler does
not appear to support long options but the "top-level" `mkfs` command
does. Therefore one option is converted while the passed through option
is not.
