feat(tvix/eval): Add passthru build for benchmark binaries

Browse source 
Add a new derivation target to the passthru of tvix.eval that builds the
benchmark binaries, *and* copies them to the outupts of the derivation
via the (somewhat arcane) `copyBinsFilter` jq script arg to naersk. This
is a bit annoying because (as far as I can tell) the derivations
returned by naersk aren't directly overridable, so we have to explicitly
fixpoint the attrs we're passing.

Also, since this is now a separate target to build the benchmarks, we
can remove `--all-targets` from the build of `tvix-eval` itself since
that was only added to build benchmarks in CI, and make
regular (non-benchmark) builds a bit faster.
