cuirass: Hard code Guile load paths.

* configure.ac (bin/cuirass, bin/evaluate): Let 'make' generate them.
* bin/cuirass.in: Hard code load paths to find Cuirass modules.
* Makefile.am (do_subst): Update substitution.
(bin/cuirass, bin/evaluate): New rules.
(EXTRA_DIST): Distribute 'bin/cuirass.in' and 'bin/evaluate.in'.
(MOSTLYCLEANFILES): Add '$(bin_SCRIPTS)'.
(install-exec-hook): New target.
(local_load_path, local_load_compiled_path): New variables.
(AM_TESTS_ENVIRONMENT): Set Guile load paths.
* build-aux/pre-inst-env.in: Don't modify Guile load paths.
