Taustubs: Remove token output

Created by: sarats

While running XGC, each rank prints the following in the log:

token: /autofs/nccs-svm1_sw/summit/.swci/1-compute/opt/spack/20180914/linux-rhel7-ppc64le/gcc-4.8.5/darshan-runtime-3.1.7-uwak6exr43zvhu2vasiddrov57baf37t/lib/libdarshan.so /autofs/nccs-svm1_sw/summit/.swci/1-compute/opt/spack/20180914/linux-rhel7-ppc64le/pgi-18     .10/spectrum-mpi-10.2.0.11-20190201-fifj65soewhhhm6xhhzad3ilgp4hmgde/lib/libpami_cudahook.so
