Currently we produce wrong drvPaths for a large number of packages
that use fetchurl (but not fetchurlBoot, which is what stdenv uses).
A simple reproducer is `pkgs.perl538`.
I debugged this down to the root cause, which is the fact that tvix
doesn't realize that the mapping from FOD-paths to outputHash is
*NOT* a 1:1 mapping. It is a many-to-one mapping. You can have
lots of different FODs with the same outputHash or even the same
outPath. For example, perl538.src and perldevel.src use the same
source tarball but a different `version`.
Anyways, I have found the root cause but have run out of time for a
while, so I've added a panic!() to in the spot where we have a logic
bug in order to call it out.

Nixpkgs tries to `import` the value returned by
`builtins.unsafeGetAttrPos`, which in our case is the file
`/deep/thought`. Since that doesn't exist, tvix-glue panics, but
there's no interpreter backtrace to follow.
Let's return an Err instead of panicking.

There's various bits and pieces in tvix-cli that use both the store and
evaluator, as well as nix-compat. For example, builtins.derivation, as
well as the reference scanning implementation.
This "glue code" currently isn't accessible from anywhere else, but it'd
be very useful if it were.
Move it out into a `glue` crate, and make `tvix-cli` a consumer of it.
All the KnownPaths setup and passing around, as well as NIX_PATH
handling is also something that should probably be moved into the glue
crate as well, but that's something left for a future CL.
