t/jobs/t0033: add test for the log file format

Add a test to check the log file format which is described in the "Log
File Format" section in HOWTO.rst. Generate log files using combination
of options relevant to log files, and check that lines in log files have
the format expected. This test helps to confirm that the changes in the
log file related functions do not cause regressions.
