tools lib traceevent: Rename input arguments of libtraceevent APIs from pevent to tep

Input arguments of libtraceevent APIs are renamed from "struct
tep_handle *pevent" to "struct tep_handle *tep". This makes the API
consistent with the chosen naming convention: tep (trace event parser),
instead of the old pevent.
