gnu: Fix packages that were importing Guile modules from the host.

Those packages were importing (ice-9 match) & co. from the host Guile,
which could potentially lead to different derivations depending on the
Guile in use.

Uncovered by the warning emitted by 'gexp-modules'.

* gnu/packages/admin.scm (inxi-minimal)[arguments]: Remove Guile modules
from #:modules.
* gnu/packages/dns.scm (ddclient)[arguments]: Likewise.
* gnu/packages/tex.scm (texlive-latex-koma-script)[arguments]: Likewise.
* gnu/packages/java.scm (openjdk11)[arguments]: Likewise for #:imported-modules.
