fix error autocompiling parts of the compiler; make check works

* libguile/load.c (scm_try_autocompile): Punt if compiled-file-name does
  not resolve, which would indicate that the file in question is part of
  the compiler itself.

* test-suite/tests/elisp.test: Today I was an evil one -- disable
  autocompilation for the elisp tests, as they are meant only for the
  memoizer's eyes. Hopefully Daniel will fix this :-)
