zoltan: add scotch library dependency (#50163)

* zoltan: add scotch library dependency

Due to the way the shared library is built it does not pick up
dependencies to other shared libraries correctly. This adds the library
dependency manually in the same way it is already done for parmetis.

* add tukss as maintainer for zoltan
