Fix for Apple DWARF5

[COJIDAT]

XCode26 change section name

[davea42]

Could you provide a small or medium sized, non-proprietary, object so I can add it to the regressiontests?
Puzzles me why no change to dwarf_machoread.c was required.
As the pull request is, I don't understand how it can work.

Hi. I revert changes in dwarf_setup_sections.c , for our code make mapping as in dwarf_machoread.c (SectionNames MachO <-> DWARF).
dwarf_machoread.c read section name sized of 16byte as result suffix __DWARF will be deleted.

In attach Dwarf file from test project.
DwarfTest.zip

Thank you very much for the testcase. I see there are issues. Several issues. From dwarfdump, via libdwarf..
I will be looking into these issues, hopefully today.

Here is the output of readobjmacho (build via my readelfobj-code github project).
Note that libdwarf dwarf_machoread.c already deals with all
the __debug* sections mentioned, renaming to standard DWARF section names.

Merged using command-line instructions and then
updated so project coding standards followed (about line length).

Thank you very much for the fix.
