tools lib traceevent: Introduce pevent_filter_strerror()
The pevent_filter_strerror() function is for receiving actual error
message from pevent_errno value. To do that, add a static buffer to
event_filter for saving internal error message
If a failed function saved other information in the static buffer
returns the information, otherwise returns generic error message.
