removing the version number is also confusing because the derivation name will use a version different than the src's but keeping it breaks luarocks builder. I need to address that.

We run pytest with `--forked` in nixpkgs, to reduce side effects that
can occur when multiple tests mutate their environment in incompatible
ways.

Forking on macOS 10.13 and later is unsafe when an application does work
between calls to fork() and its followup exec(). This may lead to
crashes when calls into the Objective-C runtime are issued, which will
in turn coredump the Python interpreter.

One good reproducer for this scenario is when the urllib module tries
to lookup proxy configurations in `urllib.request.getproxies()` through
`get_proxies_macos_sysconf` into the native `_scproxy` module.

This is a class of issues that is of course not limited to the urllib
module. The general recommendation is to use `spawn` instead of `fork`,
but we don't have any influence on upstream developers to do one or the
other.

One often cited workaround would be to disable fork safety entirely on
calls to `initialize()`, which is probably a better solution than
running without multithreading (slow) or without the `--forked` (prone
to side effects) mode.

This currently happens on aarch64-linux only, where we use more recent
11.0 SDK version, while x86_64-darwin has been stuck on 10.12 for a
while now.

Typically the actual wheel will be unchanged, but it is possible we use
the relax deps hook modifying the wheel.

right now the src is ignored in:

```
  lush-nvim = buildNeovimPlugin {
    pname = "lush.nvim";
    version = "2022-08-09";
    src = fetchFromGitHub {
      owner = "rktjmp";
      repo = "lush.nvim";
      rev = "6b9f399245de7bea8dac2c3bf91096ffdedfcbb7";
      sha256 = "0rb77rwmbm438bmbjfk5hwrrcn5sihsa1413bdpc27rw3rrn8v8z";
    };
    meta.homepage = "https://github.com/rktjmp/lush.nvim/";
  };
```

which is very confusing. With this PR, we correctly override the src and
the version of the package. We introduce a rockspecVersion attribute of
lua package to be able to still find the rockspec when the
"version" field needs to be different than "rockspecVersion".
