rust-hgpath: add `repr(transparent)` to `HgPath`

It's been stabilized a long time ago, so let's not rely on an implementation
detail now.

-// `HgPath::new()` current implementation relies on `Slice` being
-// layout-compatible with `[u8]`.
-// When attribute privacy is implemented, `Slice` should be annotated as
-// `#[repr(transparent)]`.
-// Anyway, `Slice` representation and layout are considered implementation
-// detail, are not documented and must not be relied upon.
