Add resiliency in UE against interrupted HTTP downloads.

Currently when there's an interruption in the HTTP transfer, update_engine
attempts to resume the transfer only 3 times. After that it gives up.
For reasons yet to be investigated (31019), this happens quite consistently
on ARM and hence we need to fix update_engine to be more resilient in such
cases.

The fix is to increase the retry count to 20 for post-OOBE case. We'll
still maintain the original limit of 3 retries for OOBE case so as to not
stall OOBE forever.

TEST=Existing unit tests hit all new code paths and pass. Manually tested
     on ZGB and Kaen.
