These tests have been collected from nixpkgs f870c6ccc8951fc48aeb293cf3e98ade6ac42668
usage of builtins.match for x86_64-linux eval system. At most 2 matching and
non-matching cases are included for each encountered regex. This should
hopefully add more confidence when possibly trying to switch the regex implementation
in the future.

This overload isn't actually necessary anywhere and
doesn't make much sense. The pointers to `Value`s are
themselves const, but the `Value`s are mutable.
A non-const member function implies that the object itself
can be modified but this doesn't make much sense considering
the return type: `Value * const * `, which is a pointer
to a constant array of pointers to mutable values.

Running parallel nix in nix can lead to multiple instances trying to
create the state directories and failing on the `createSymlink` step,
because the link already exists.

`replaceSymlink` is already idempotent, so let's use that.
