build: build proper VMDK formats for ESXI 6.5

VMWare ESXI 6.5 and above is not compatible with
subformat=monolithicSparse (The default qemu-img convert -O VMDK option).
Monolithic Sparse vmdk can be imported, but issues occur when running
sysupgrade with new images and other tasks that modify the file system
(issues like Kernel panics, reboot loops, sometimes crashing the Host ESXI
box).

This change creates an additional VMDK output file for ESXI that sets the
subformat to monlithicFlat, and the adapter_type to the SCSI lsilogic
controller.

This change existed back on:
25e36d379e73d64d6316fae9dc841c5ef28980f1

But it looks like the change was removed when refactoring occurred with:
5f6a2732f892b6229473576d89cc963ae9c97d5d
