I didn't read the code closely enough -- emacs-server already does this,
but only deletes the /tmp/emacs0/server socket, but leaves the directory
behind.  As you say, there may be more than one server (with different
names), so deleting the directory may fail, but the final Emacs that
exits should successfully delete directory, at least, and I've added
that to Emacs 28.
