Subject: [PATCH] tab: correctly handle options request.

Because a `Tab` is an `OpenStruct` the existing calls to
`any_args_or_options?` would always return `false`. This means that
`Formula#declared_runtime_dependencies` would never call
`Tab#without?` to check whether a dependency has been brought in by an
option.

Fixes #4407
