tools lib traceevent, perf tools: Rename 'enum pevent_flag' to 'enum tep_flag'

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
pevent_get_page_size API and enum pevent_flag to enum tep_flag
