[iso] enable persistence support for Linux Mint

* Mint users sure are lucky that one of them *lied their way through* pretending that
  persistence actually used to work with previous version of Mint, when it never did,
  because they got us going through a whole refactor of the partition creation process
  just so we could make Mint persistence work.
* Closes #2428.
* Also fix a Coverity warning.
