picolisp: fix help functionality
Currently, trying to use help results in something like this:

```
: (help 'db)
========================================
w3m: Can't exec
=======================================
```

By including `w3m` as an input, the behaviour changes to:

```
: (help 'db)
========================================
(db 'sym 'cls ['hook] 'any ['sym 'any ..]) -> sym | NIL
Returns a database object of class cls, where the values for the sym arguments
correspond to the any arguments. If a matching object cannot be found, NIL is
returned. sym, cls and hook should specify a tree for cls or one of its
superclasses. See also aux, collect, request, fetch, init and step.

========================================
-> db
```
