This mostly affected attribute parsing (due to the syn::Meta changes).
Also creating `DelimSpan`s for custom-built `syn::Attribute`s is a
bit... ugly.
Upshot: turns out we can drop some helpers in util.rs with the new
`syn::Meta` changes.

This allows fixing up things such as `skip_serialize_if`
calls like so:
#[derive(Updater)]
struct Foo {
#[serde(skip_serializing_if = "MyType::is_special")]
#[updater(serde(skip_serializing_if = "Option::is_none"))]
field: MyType,
}
