services: configuration: Revert to a working ‘guix home’.

This reverts commit 543d971ed2a1d9eb934af1f51930741d7cc4e7ef, and
its dependent commit 9b21cd2e9a614f1937769caf3917a791b151d841, which
appear to have triggered a recent wave of ‘guix home’ regressions
involving (services (list (service home-bash-service-type))):

In gnu/home/services/shells.scm:
    504:7  3 (home-bash-extensions #<<home-bash-configuration> package: #<package bash@5.1.8 gnu/packages/ba…> …)
In unknown file:
           2 (append #<<location> file: "…" line: 14 column: 12> ())
In ice-9/boot-9.scm:
  1685:16  1 (raise-exception _ #:continuable? _)
  1685:16  0 (raise-exception _ #:continuable? _)

ice-9/boot-9.scm:1685:16: In procedure raise-exception:
In procedure append: Wrong type argument in position 1 (expecting empty list): #<<location> file: "…" line: 14 column: 12>

I should love to dive in & fix this rather than revert, but urgently
need sleep.
