bug#41145: 27.0.91; small issues with `display-fill-column-indicator' Customization group

[Stefan Monnier]

Actually, there is a defcustom there (in the expansion of
`define-globalized-minor-mode`).

I'd get rid of the file and move its content to one of the
preloaded files (simple.el?  faces.el?  fill.el? ...)
