Use patched nebula os package gradle plugin (#100280)

There is a bug in the nebula os package gradle plugin that breaks copy spec specific setgid handling.
We have created a patch for the plugin that we use for now to unblock us. This will be ported upstream
to the nebula main branch and part of a release but that requires some more polishing and will
be taken care of in a later PR
