Upgrade proof tool submodules (#102)

* Upgrade proof tool submodules

This commit advances Litani to release 1.10.0, and the starter kit to
the tip-of-tree. This brings the following improvements:

- Profiling
    - Litani measures the memory usage of the CBMC safety checking and
      coverage checking jobs
    - The dashboard includes box-and-whisker diagrams for memory use per
      proof
    - The dashboard includes a graph of how many parallel jobs are
      running over the whole run, making it easy to choose a CI machine
      with enough parallelism
    - It is now possible to designate particular proofs as "EXPENSIVE";
      Litani runs expensive proofs serially, ensuring that they do not
      over-consume resources like RAM.

- UI improvements
    - Each pipeline page includes a table of contents
    - Each pipeline page includes a dependency graph of the pipeline
    - Each job on the pipeline page has a hyperlink to that job
    - The terminal output is now less noisy

* Symlink run-cbmc-proofs.py to starter kit

The run script is now a symbolic link into the starter kit submodule,
meaning that it will be updated whenever the starter kit is. This is
done iso that E-SDK doesn't carry custom modifications to the run script
unless necessary; previous commits have made the E-SDK proofs consistent
with the generic starter kit conventions.
