[PATCH] test: test_trace.py: Have trace-cmd report always use -l

[Tom Rini]

With newer versions of trace-cmd the report subcommand will have
different output from before if we do or do not pass -l. However, with
the -l flag passed our put is consistent here. This updates our regular
expressions and comments for this as well now.

Signed-off-by: Tom Rini <trini at konsulko.com>

Changes in v2:
- Use the -l flag to have consistent output for either version
