bournish: Prevent inlining of run-time support procedures.

On Guile 3, those procedures could be inlined, leading to
unbound-variable errors:

  scheme@(guile-user)> ,bournish
  Welcome to Bournish, a minimal Bourne-like shell!
  To switch back, type `,L scheme'.
  bournish@(guile-user)> ls
  ice-9/boot-9.scm:1669:16: In procedure raise-exception:
  Unbound variable: ls-command-implementation

Reported by Ricardo Wurmus.

* guix/build/bournish.scm (define-command-runtime): New macro.
(ls-command-implementation, wc-command-implementation)
(wc-l-command-implementation, wc-c-command-implementation): Use it
instead of 'define'.
