afdoupdateebuild is breaking chrome pfq

Project Member Reported by manojgupta@chromium.org, Apr 7 2018

Issue description

https://uberchromegw.corp.google.com/i/chromeos/builders/master-chromium-pfq/builds/6153

22:13:18: INFO: Found latest AFDO info file gs://chromeos-prebuilt/afdo-job/llvm/latest-chromeos-chrome-amd64-67.afdo but it is too old
22:13:18: ERROR: Could not find appropriate AFDO profile
22:13:18: INFO: Translating result Could not find appropriate AFDO profile to fail.

Root cause is AFDODataGenerate in chell-chrome-pfq is broken as create_llvm_prof cannot parse new perf events.

there is already a fix for this from lakshmana@. 
The next PFQ run should fix the issue.
There might also be some problem in email notifications:
