9b752fd0e1 buildRustPackage: Don't hardcode registry index hash
Instead, discover it automatically when building the package.

This makes `buildRustPackage` more future-proof with respect to changes
in how `cargo` generates the hash.

Also, it fixes broken builds in i686 because apparently, cargo generates
a different registry index hash in this architecture (compared to
x86-64).

d6093505cc buildRustPackage: Get rid of /proc/self/cwd hack
This makes buildRustPackage portable to non-Linux platforms.

Additionally, now we also save the `Cargo.lock` file into the fetch output, so
that we don't have to run $cargoUpdateHook again just before building.

b993c2113c buildRustPackage: Add a mechanism to patch registry deps
... in a more generic way.

With this commit, if you need to patch a registry package to make it
work with Nix, you just need to add a script to patch-registry-deps
in the same style as the `pkg-config` script.

0cde1dc524 cargo: Remove setupHook
Instead, move that code into buildRustPackage.

The setup hook was only doing part of the work anyway, and having it in
a separate place was obscuring what was really going on.

e42c17ee97 buildRustPackage: Fix Cargo.lock being ignored
It turns out that `cargo`, with respect to registry dependencies, was
ignoring the package versions locked in `Cargo.lock` because we changed
the registry index URL.

Therefore, every time `rustRegistry` would be updated, we'd always try
to use the latest version available for every dependency and as a result
the deps' SHA256 hashes would almost always have to be changed.

To fix this, now we do a string substitution in `Cargo.lock` of the
`crates.io` registry URL with our URL. This should be safe because our
registry is just a copy of the `crates.io` registry at a certain point
in time.

Since now we don't always use the latest version of every dependency,
the build of `cargo` actually started to fail because two of the
dependencies specified in its `Cargo.lock` file have build failures.

To fix the latter problem, I've added a `cargoUpdateHook` variable that
gets ran both when fetching dependencies and just before building the
program. The purpose of `cargoUpdateHook` is to do any ad-hoc updating
of dependencies necessary to get the package to build. The use of the
'--precise' flag is needed so that cargo doesn't try to fetch an even
newer version whenever `rustRegistry` is updated (and therefore have to
change depsSha256 as a consequence).

d648be6724 buildRustPackage: Add check phase and enable it by default
Also disable check phase in cargo as there are lots of failures (some
probably due to trying to access the network).
