tools/perf: Add '__rel_loc' event field parsing support
Add new '__rel_loc' dynamic data location attribute support.
This type attribute is similar to the '__data_loc' but records the
offset from the field itself.
The libtraceevent adds TEP_FIELD_IS_RELATIVE to the
'tep_format_field::flags' with TEP_FIELD_IS_DYNAMIC for'__rel_loc'.
