New setting to mark postinstall as optional.

This setting allows to mark a postinstall script as optional. This
allows the postinstall program to fail when it is not strictly required
to run for the update to succeed.

Bug: 27178350
TEST=Added unittest. Sideloaded an update with an optional postinstall.
