Update prebuilt_etc available for snapshot
Make prebuilt_etc module available for the snapshot. This change
includes implementing snapshot interface for the prebuilt_etc module so
it can be added to the snapshot from the fake snapshot, or when the
module is specified in the list.
Bug: 192430376
Test: m nothing passed
Test: Checked if the module is included in the snapshot properly
