Wer should use -q while unzipping layout-test-results.zip in ews. By default unzip command lists all the filnames inside the zip, which can be thousands of files. We don't need to log all these, and store all this data in the buildbot database. This command is also run on the server, and disabling this logging might also have small performance improvement.

For e.g.: In https://ews-build.webkit.org/#/builders/17/builds/4344/steps/12/logs/stdio there were over 50000 lines (taking few megabytes of space in the database).
