Updated nightly build

Speed up the source package build

lintian accounted for more than half the wall clock of a
Jenkinsfile.sourcepackage run: for a source package it unpacks the
whole openmodelica orig tarball again and scans every file, once per
built revision. Nothing consumes its output - it is neither archived
nor gated on - so drop it with debuild --no-lintian. That also removes
a failure mode where a new lintian version invents an error tag and
fails the nightly.

Compress the orig tarball with `xz -T0` instead of tar's single
threaded `cJf`. Same preset, so the tarball only grows a fraction of a
percent from the block splitting, and it decompresses in parallel too.
Note this wants roughly 100 MB of encoder memory per core; pin the
thread count if that ever gets tight on the builder.
