BuildRustCrate: more general overrides, and handling the "dylib" crate type (#35171)

* buildRustCrate: adding a symlink from libblah-xxxxx.so to libblah.so
* BuildRustCrate: overriding phases
* Carnix: 0.6.5 -> 0.6.6
* Fixing symlink_dependencies --buildDep
* Shorter symlink_dependencies
* running `runHook postBuild` *after* the build

## Compiling Rust crates using Nix instead of Cargo
### Simple operation
When run, `cargo build` produces a file called `Cargo.lock`,
containing pinned versions of all dependencies. Nixpkgs contains a
tool called `carnix` (`nix-env -iA nixos.carnix`), which can be used

will fetch it from [crates.io](https://crates.io). A `sha256`
attribute is still needed for Nix purity.
### Handling external dependencies
Some crates require external libraries. For crates from
[crates.io](https://crates.io), such libraries can be specified in
`defaultCrateOverrides` package in nixpkgs itself.

Actually, the overrides introduced in the previous section are more

- Extra arguments to be passed to `rustc`:

```
- Phases, just like in any other derivation, can be specified using
the following attributes: `preUnpack`, `postUnpack`, `prePatch`,
`patches`, `postPatch`, `preConfigure` (in the case of a Rust crate,
this is run before calling the "build" script), `postConfigure`
(after the "build" script),`preBuild`, `postBuild`, `preInstall` and
`postInstall`. As an example, here is how to create a new module
before running the build script:
```
(hello {}).override {
preConfigure = ''
echo "pub const PATH=\"${hi.out}\";" >> src/path.rs"
'';
};
```
### Features
One can also supply features switches. For example, if we want to
compile `diesel_cli` only with the `postgres` feature, and no default
features, we would write:
