addr2info.c: Make it work with --enable-yjit

Background: GCC 12 generates DWARF 5 with .debug_rnglists, while rustc
generates DWARF 4 with .debug_ranges.

The previous logic always used .debug_rnglists if there is the section.
However, we need to refer .debug_ranges for DWARF 4.

This change keeps DWARF version of the current compilation unit and use
a proper section depending on the version.
