Support Factory OTA for Virtual A/B devices

Browse Source 
In Factory OTA, secondary payload should be generated without
virtual_ab flag set, so that update package generator generates
a regular A/B OTA (with snapshot_enabled set to false), and
OTA client writes system_b without snapshots.

Test: apply secondary OTA
