[nlinum] Show deprecation (Emacs 26.1+) warning on startup

Browse source 
The warning:
nlinum layer is deprecated for Emacs 26.1 and above
wasn't shown until SPC h SPC was pressed.

Because the variable: configuration-layer--used-layers
wasn't populated before the warning check occurred in
nlinum/packages.el.

The solution (suggested by syl20bnr) was to move the
check to a new file: nlinum/config.el.
