fix(content): handle virtualbox case where DMI Memory Devices are reported as [null]
when testing a virtualbox VM, the DMI.Memory.Devices from jq came back as [null] this change allows the collect inventory jq to succeed in that edge case there were 2 issues:
- the null was breaking jq, protected with //[]
- the empty return was breaking the assignment, changed to //[]
should have no other impact.
