Derivations can output "text-hashed" data In particular, this means that derivations can output derivations. But that ramification isn't (yet!) useful as we would want, since there is no way to have a dependent derivation that is itself a dependent derivation.

Fix texted hash output test to work when testing daemon Need to get experiment features to daemon like with the other tests.

# In the corresponding nix file, we have two derivations: the first, named root,
# is a normal recursive derivation, while the second, named dependent, has the
# new outputHashMode "text". Note that in "dependent", we don't refer to the
# build output of root, but only to the path of the drv file. For this reason,
# we only need to:
#
# - instantiate the root derivation
# - build the dependent derivation
# - check that the path of the output coincides with that of the original derivation
