Fix reliability when KOKKOS_PROFILE_LIBRARY is set in env (#103)

* Fix reliability when KOKKOS_PROFILE_LIBRARY is set in env

- in certain situations, an exe using kokkos may be instrumented
- this will cause libomnitrace to be dlopened via libomnitrace-dl
- if KOKKOS_PROFILE_LIBRARY is set to libomnitrace and not libomnitrace-dl, you will end up with different instances of libomnitrace trying to collect data

* Set OMNITRACE_MAX_THREADS=32 in CI
