Remove some unnecessary bindings of same-window-* variables.

* lisp/progmodes/python.el (python-shell-get-process-name): Don't mess
with same-window-buffer-names.

* lisp/eshell/eshell.el (eshell-add-to-window-buffer-names)
(eshell-remove-from-window-buffer-names): Make obsolete.
(eshell-buffer-name, eshell-unload-hook): Don't use them.
(eshell): Just use pop-to-buffer-same-window instead.
