Make sure core Eshell modules are loaded

Previously, if you removed all (or most) extension modules from
Eshell, it failed to load esh-var.el, meaning that you couldn't use
variable expansions.  To avoid this issue, we now explicitly load the
core modules in esh-mode.el.

* lisp/eshell/esh-mode.el: Explicitly require core Eshell modules.
