Title: Strip whitespace from depends

This was flagging our cookbooks incorrectly for FC007 due to the way we
specify long list of dependencies.

```ruby
%w[
apt
build-essential
git
python
ark
runit
firewall
].each do |dep|
depends dep
end
```

Having the names indented means they're actually strings like " apt"
which is how the ast sees them.

```
[0]

```

The leading space doesn't actually matter though since knife strips the
whitespace when it's building metadata.json.

The correct place to fix this is probably in the AST but I think that's
way outside my skillset.
