Re-submit r289925 (Update .debug_line section version to match DWARF version)

Set the .debug_line version to match the requested DWARF version,
except with a maximum of v4 because we don't support v5 yet.

Previously Chromium had issues with this patch; see PR31407.  Chromium
tool issues have been addressed, so hopefully this will go through
this time.

Patch by Katya Romanova!
