gnu: Use full versions in the variable names of Rust library development snapshots.

This handles version changes better and brings in less confusion when learning
the packaging process.

* gnu/packages/rust-sources.scm (rust-pipewire-for-niri): Rename variable to...
(rust-pipewire-0.8.0.fd3d8f7): ...this.
(rust-pubgrub-for-uv): Rename variable to...
(rust-pubgrub-0.3.0.b70cf70): ...this.
(rust-smithay-for-niri): Rename variable to...
(rust-smithay-0.6.0.ede2707): ...this.
(rust-web-view-for-alfis): Rename variable to...
(rust-web-view-0.7.3.82d7cbc): ...this.
* gnu/packages/rust-crates.scm: Adjust accordingly.
