CONFIG: additional packaging helpers, tutorial test helper

- bin/tools/create-mpi-config to query/write values for system openmpi.
  In some cases this can be used to avoid an mpicc requirement at runtime.

- adjust openfoam session to include -test-tutorial forwarding to the
  tutorials/AutoTest. This helps with writing installation tests.

- adjust foamConfigurePaths to latest version

- removal of gperftools default config, as per develop
