This replaces the `versionCheckDontIgnoreEnvironment` parameter. Keeping
all environment variables is still possible by using
`versionCheckKeepEnvironment = "*";`.
Motivation for this hook is simple: there's no single documented
way to do trivial things with ctest:
1. Pass additional flags to ctest invocation.
2. Selectively disable tests in a mechanism similar to python's
`disabledTests` or rust's composable skips in `checkFlags`.
3. Disable parallel checking.
Current state of things has lead to several different solutions:
1. Completely overriding `checkPhase` [1] and invoking ctest manually
with the necessary flags. This is most often coupled with `-E` for
disabling test or setting parallel level.
2. Wrangling with weird double string/regex escaping and trying to stuff
additional parameters and/or exclusion regex via `CMAKE_CTEST_ARGUMENTS`.
This approach is especially painful when test names have spaces. This is
the reason I originally decided to implement this hook after wrangling with
failing darwin tests here [2].
3. Stuffing additional arguments into `checkFlagsArray` with the
`ARGS` makefile parameter [3].
I don't see any reason to keep the status-quo. Doing something along these
lines has been suggested [4] for both `ctest` and `meson`. Meson setup-hook
has switched from `ninja` to `meson` in [5] with little friction. Doing
the same for cmake in a single sweep would prove problematic due to the
aforementioned zoo of workarounds and hacks for `ctest`. Doing it via
a separate hook would allow us to refactor things piecemeal and without
going through staging. The benefit of the hook is immediately clear and it
would allow to drive the refactor tractor at a comfortable pace.

Cargo 1.84.0 broke fetchCargoTarball hashes, so fetchCargoTarball is
not long for this world. Tell people to use fetchCargoVendor, which
Nixpkgs is currently in the process of switching to across the tree.
