perf dwarf-aux: Add die_find_func_rettype()
The die_find_func_rettype() is to find a debug entry for the given
function name and sets the type information of the return value. By
convention, it'd return the pointer to the type die (should be the
same as the given mem_die argument) if found, or NULL otherwise.
