test(3p/nix): Partially enable evaluator success tests
Enables the `eval-okay-` test suite, with some caveats: * The output is not yet checked against the expected value, so the tests only check that pure evaluation succeeds * A handful of tests have been disabled as they are causing failures that may be related to the DummyStore implementation. Both of these will be addressed in followup commits, but there is already some value in having the pure evaluation tests pass.

These tests are disabeld primarily because the DummyStore used for
|
||||
tests does not interact with real files on disk at the moment, but the
|
||||
tests expect it to.
|
||||
|
||||
Once we have a solution for this (potentially just reading & hashing
|
||||
the files, but not writing them anywhere) these tests will be enabled
|
||||
again.
