perf tools: Remove HAVE_LIBTRACEEVENT_TEP_FIELD_IS_RELATIVE

Switch HAVE_LIBTRACEEVENT_TEP_FIELD_IS_RELATIVE to be a version number
test on libtraceevent being >= to version 1.5.0. This also corrects a
greater-than test to be greater-than-or-equal.

Fixes: b9a49f8cb02f0859 ("perf tools: Check if libtracevent has TEP_FIELD_IS_RELATIVE")
