guilt: explicitly call for bash

Running complex guilt stacks of patches/commits can cause interesting
failures after ~20m of processing, with errors like "Bad substitution".

These have been traced back to having /bin/sh -->  /bin/dash on Ubuntu
systems.  Putting a shell that actually *works* (such as /bin/bash)
in as /bin/sh makes the problem go away.  So here we change the guilt
scripts to explicitly call for bash to ensure we don't have a similar
issue after deployment.
