Move code quality and dependency scan to build instead of deploy stage

The codequality and dependency scan steps have no antecedents, and codequality takes about 10 minutes. Running these in parallel with the main build during the build stage (instead of deploy stage) will speed up the total execution time of www-gitlab-com pipelines from about 30 to 20 or so minutes.

Not sure when it broke, but this also fixes an issue where the codeclimate output file had a different name in actuality vs. the one listed in the .gitlab-ci.yml. Code quality results should once again be captured.
