read-print: Correctly support multiple same-named newline forms.
Previously (home-environment (services ...)) would not be considered a
"newline form". This fixes it.
* guix/read-print.scm (newline-form?): Use 'vhash-foldq*' instead of
'vhash-assq' and iterate over candidates.
* tests/read-print.scm: Add test.
