reverting to old tinyscheme

* there is a critical bug that crashes passdb when loading and evaluating
  a pass
* tinyscheme-1.41 issues a segfault at tinyscheme/scheme.c:1205 (1.41)
* tinyscheme1.38 works on the same `rules.scm` file
* I have the `rules.scm` file causing issues but I don't know why it's
  happening so I don't have a simple test case
* reverting to 1.38 for now until I can look at this in more depth
