lib/call-machine: Use a list for FS options

In NixOS/nixpkgs@edb8991 the version got bumped to 16.09, so
fileSystem.*.options no longer takes a plain string.

The original change has been introduced in NixOS/nixpkgs@3c5fca9 and we
already use it everywhere in vuizvui but not for the ISO image builder
yet.
