bug#21549: 25.0.50; winner.el: void-function cl-remove-if-not

[Mark Oteiza <mvoteiza@udel.edu>]

Hi,

The recent change to winner.el caused an error for me. `emacs -Q` has no
problem, but my init.el does.  I reduced my problematic init.el down to:

  (setq custom-file "/tmp/foo/custom.el")
  (menu-bar-mode -1)
  (winner-mode)
  (load custom-file t)

There is no issue if custom.el is empty.  I populated custom.el by doing
M-x customize-variable RET inhibit-startup-screen RET, toggling and
saving.  Starting emacs with this configuration gives the void-function
error for cl-remove-if-not. The backtrace buffer appears to be empty
when starting with --debug-init.
