tracing/filters: allow user-input to be integer-like string
Suppose we would like to trace all tasks named '123', but this
will fail:
# echo 'parent_comm == 123' > events/sched/sched_process_fork/filter
bash: echo: write error: Invalid argument
Don't guess the type of the filter pred in filter_parse(), but instead
we check it in __filter_add_pred().
[ Impact: extend allowed filter field string values ]
