Fix ASDF loading for ABCL
Updates compileit.lsp since I forgot in !55 (merged)
Also ignore errors in the sandbox path. This works for ABCL because rt.lisp gets loaded first by ASDF then by either doit.lsp or compileit.lsp. A better fix would be for it to work both times. If this hack fixes ABCL's usage of ansi-test then I'll come up with a better fix.
@mevenson Can you try this?
