Previously, if the lisp-invocation library was not there, we would simply skip this test (relatively quietly -- the skip was not visible at the end of the run). I have changed this so that the test fails in that case. There's no need to skip any longer, since the tester will have lisp-invocation available in the ASDF repository as a git submodule. This will help avoid problems we've had, as most recently with JCB, who checked out a fresh ASDF, and believed all was well, because absent a git submodule initialization, test-program.script was skipping, rather than failing. Please report any issues, R
