Allow update_device install the secondary payload

Add an option to support installation of the secondary payload. This is
used to verify an android factory OTA, where it has one step to install the
secondary payload. The payload and its property file store under the
secondary/ directory of the update package.

Test: install a secondary payload from a factory OTA package
