bump minimum Rust version to 1.85

nbdd0121 · nbdd0121 · commit 8ea54512f5a7 · 2026-04-14T14:25:00.000+01:00
Following the kernel minimum version bump in f32fb9c58a5b ("rust: bump Rust
minimum supported version to 1.85.0 (Debian Trixie)"), pin-init can bump
its minimum version to 1.85, too.

This removes the `lint_reasons` feature which is stabilized in 1.81 and the
`raw_ref_ops` and `new_uninit` features which are stabilized in 1.82.
