perf probe: Fix finder to find lines of given function
The commit ba28c59bc9ed8fb7b9a753cd88ee54a2c4f6265b fixed a declaration entry bug in probe_point_search_cb(). There are same bugs in line finder and call_probe_finder(). This introduces a new dwarf utility function to determine given DIE is a function definition, not declaration.
