bug#34180: 27.0.50; argv[0] used incorrectly to find the .pdmp

[[[ foreign or domestic, requires you to follow Snowden's example. ]]]

For Emacs, finding the executable requires explicitly following
symlinks one by one and testing other related file names.
If you are thinking of using a gnulib function for this,
we need to check very carefully to make sure it does the right thing
in each and every case.

I think we made this work correctly, some months after pdumping was
added.  Did it break since them?
