Code review comment for lp:~bladernr/checkbox-certification/cert-add-cert-whitelist

Looks good and took the opportunity to rename a few jobs:

sru_attach_screenshot -> sru_screenshot_attachment
sru_xorg-failsafe -> sru_xorg_failsafe
sru_xorg-process -> sru_xorg_process
sru_fwts-wakealarm -> sru_fwts_wakealarm

And made sure to update the whitelists accordingly.
