Fix bug where 'program-arities' returns #<unspecified> (issue #23)
program-arities now returns an empty list if no arities information is found.
This fixes the bug that happens when calling, say, `(autodoc '(display))`,
which leads to following error:
```
scheme@(guile-user)> (autodoc '(display))
ice-9/boot-9.scm:1669:16: In procedure raise-exception:
In procedure map: Wrong type argument: #<unspecified>
Entering a new prompt. Type `,bt' for a backtrace or `,q' to continue.
scheme@(guile-user) [1]> ,q
```
