fix(3p/nix): Don't include depotPath in the main drv r/1466

Including depotPath in the shellHook of the main derivation for tvix
was, unsurprisingly, causing spurious rebuilds. It's still useful when
developing locally, though, so I've extracted it to a `build-shell`
derivation as a passthru attribute and updated the documentation.
