update_engine: Use helper Command::AbortWithCustomError() method

weaved now provides new variants of Command::Abort() that allow
to specify the error information as brillo::Error or binder::Status.

Command::AbortWithCustomError(brillo::Error*) also makes sure the error
code is prepended with "_", so no need to add that in OnTrackChannel().
