usb: gadget: implement and use system_partitions_get_null
system_partitions_get() clones the system partitions file list and
returns the copy. usb multi gadget code expects disabled gadgets to
have a NULL file list, not an empty one, so fastboot and DFU handle
this case. Add a new system_partitions_get_null helper that can be
used instead. This will be used for USB mass storage gadget as well
in a follow-up commit.
