update_engine: Activate CachedFileDescriptor
This patch activates CachedFileDescriptor for use in target_fd_. We
intend to use ExtentWriter for all payload operations. This patch alone
decreased the update time for a lumpy device from around 16 minutes down
to 2:30 minutes without necessarily putting pressure on memory. And that
is with O_DSYNC flag on.
