home: import: Use (guix read-print) to render the config file.

* guix/scripts/home/import.scm (manifest+configuration-files->code):
Insert calls to 'comment' and 'vertical-space'.
(import-manifest): Use 'pretty-print-with-comments/splice' instead of a
loop on 'pretty-print'.
* tests/home-import.scm (remove-recursively): New procedure.
(eval-test-with-home-environment): Use it.
