perf tools: traceevent API cleanup, remove __tep_data2host*()

In order to make libtraceevent into a proper library, its API should be
straightforward. The __tep_data2host*() functions are going to no longer
be available as a libtraceevent API, tep_read_number() should be used
instead. This patch replaces __tep_data2host*() usage with
tep_read_number() in perf.
