update_engine: Fix delta_performer_fuzzer
-Set the flag hash_checks_mandatory to true in the instance of
InstallPlan in the fuzzer. This allows the delta performer to perfom
aditional checks which prevent incosistencies between the manifest size
in the payload and the one reported by Omaha.
-Stop the fuzzer test if the Write function returns false.
-Fix a few minor typos.
