rust: simplify Clippy warning flags set
All Clippy lint groups that we enable, except `correctness`, have a
default `warn` level, thus they may be removed now that we relaxed all
lints to `warn`.
Moreover, Clippy provides an `all` lint group that covers the groups
we enable by default. Thus just use `all` instead -- the only change is
that, if Clippy introduces a new lint group or splits an existing one,
we will cover that one automatically.
In addition, `let_unit_value` is in `style` since Rust 1.62.0, thus it
does not need to be enabled manually.
