checkInputs used to be added to nativeBuildInputs. Now we have
nativeCheckInputs to do that instead. Doing this treewide change allows
to keep hashes identical to before the introduction of
nativeCheckInputs.
The latest bcrypt version segfaults during test_kdf, which prevents the
package from building. The package is in the critical chain for many
NixOS tests, which currently won't complete on i686-linux.
