TT#34302 Create /tmp/ngcp with tmpfiles.d, remove .preinst

After removing the changes to /etc/default/ngcp-panel in a previous commit, the
.preinst script's only purpose is to create /tmp/ngcp, which can be better done
with tmpfiles.d, and so this script can be removed.

(The original idea and plan is from Alex Lutay, cheers to him).
