tools/offcputime: Fix python3 string output
When using non-folded output, some of the strings would
be printed as raw byte arrays on python3, like this:
b'finish_task_switch'
b'__schedule'
b'schedule'
b'worker_thread'
b'kthread'
b'ret_from_fork'
- kworker/u16:1 (22022)
2267942
This commit updates the code to treat these as utf8 strings,
consistent with all the other strings printed from this tool.
