Dave Laing 4d5371f373 nixos/virtualbox: Adds more options to virtualbox-image.nix (#42699)
* nixos/virtualbox: Adds more options to virtualbox-image.nix

Previously you could only set the size of the disk.

This change adds the ability to change the amount of memory
that the image gets, along with the name / derivation name /
file name for the VM.

* Incorporates some review feedback
