[OPS] Ignore unzip warnings

Prior to this change, we had an agent release where customers were getting unzip errors.

This change ignores that warning to mitigate that issue.

 * Unit Tests : [N]
 * Integration Tests : [N]
 * Was waiting on customer to test this fix, but have not got a response and since we're disabling auto update, we are plannning to use this fix.
 * Have manually tested this agent on an ubuntu and amazon linux box.
