Include a newline at the end of operation event logs

[pirxthepilot]

Description

Operation event logs do not terminate with a newline, which causes certain log forwarding agents not to process the line. In addition, not having the newline seems to break the POSIX definition of a line, defined as:

A sequence of zero or more non- characters plus a terminating character.

How Has This Been Tested?

I verified that adding os.linesep after json.dumps() works. I also expect the test_writing_event_logs_to_disk test to pass without issue.

Hmm, not sure how to fix those build errors. Looks like failure in the builds themselves?

@pirxthepilot it's not you, existing issue with branches from forks. No worries, hoping to look at PR later this week when I have a sec.
