Partially Revert 2b9d241

2b9d2417722cd4052b0e22494886f93c5b4ef042 update_engine: Update libchrome APIS to r456626.

The above commit changes the libchrome API used in update_engine to r456626. But
the libchrome has not been upreved fully in the CrOS yet with the exception of
some changes represented in UE like CL:882543. So, now we need to revert the
changes partially untill the libchrome is updated.
