Update a cranelift patch file for formatting changes.

PR #125443 will reformat all the use declarations in the repo. This
would break a patch kept in `rustc_codegen_cranelift` that gets applied
to `library/std/src/sys/pal/windows/rand.rs`.

So this commit formats the use declarations in
`library/std/src/sys/pal/windows/rand.rs` in advance of #125443 and
updates the patch file accordingly.

The motivation is that #125443 is a huge change and we want to get
fiddly little changes like this out of the way so it can be nothing more
than an `x fmt --all`.
