Mark some of the option fields as ignored in pkg/bindings

I realized that `params.Del("SkipTLSVerify")` doesn't have any
effect because keys are always lowercased. So it should really
be `params.Del("skiptlsverify")`.

There's also a little bug introduced by 3bf52aa and b1d1248: if
one passes `ProgressWriter` object having `Stringer` interface
i.e. `bytes.Buffer` it ends up been serialized in query with
`util.ToParams()`.

To circumvent both problems I propose to mark non-serializable
parameters with `schema:"-"` so there's no need to delete them from
resulting `url.Values`.
