bug#50189: wdired chmod should not follow symlinks

[Paul Eggert]

To be consistent with dired M, wdired's method of textually editing a 
symlink's permissions should also not follow symlinks. Proposed patch 
attached.

I did not test this, as I don't use wdired and couldn't get it to work 
for me regardless of whether the patch is applied.

This patch also removes some obsolete commentary about dired-chmod-program.
