[PATCH] tests: Handle zero directory entry in .debug_line DWARF5 debugedit.at

[Mark Wielaard]

We were skipping the zero directory entry, because it was always
the same as the directory entry at position one. But that isn't
true anymore with gcc 11.2.1. There the zero dir entry is unique.
Fix the debugedit.at .debug_line testcases using DWARF5 to also
include dir entry zero.
