genpolicy: Fix clippy manual_div_ceil

Browse Source 
Manually fix `manual_div_ceil` clippy warning reported by rust 1.85.1.

```console
error: manually reimplementing `div_ceil`
  --> src/verity.rs:73:25
   |
73 |             let count = (data_size + entry_size - 1) / entry_size;
   |                         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: consider using `.div_ceil()`: `data_size.div_ceil(entry_size)`
   |
   = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#manual_div_ceil
   = note: `-D clippy::manual-div-ceil` implied by `-D warnings`
   = help: to override `-D warnings` add `#[allow(clippy::manual_div_ceil)]`
```
