gnu: guile: Move Readline support to a separate 'guile-readline' package.
This reduces the closure of Guile from 131 MiB to 116 MiB and removes extra readline/ncurses builds from the bootstrap path. * gnu/packages/guile.scm (guile-2.0)[inputs]: Remove READLINE. (make-guile-readline): New procedure. (guile-readline): New variable. * gnu/system/shadow.scm (default-skeletons): Adjust '.guile' so that it gracefully deals with missing (ice-9 readline).
