libdw: dwarf_getsrclines mark highest address as end_sequence.
Make sure the highest address for the CU is marked as end_sequence.
This is required by the DWARF spec, but some compilers forget and
dwfl_module_getsrc depends on it. We could reject it as bad DWARF
but the DWARF .debug_lines spec is much stricter than what compilers
seem to output in practice.
