Fix stack --nix build

[rvl]

Overview

Addresses the following errors from stack --nix build which seem to happen with newer versions of nix:

1. Executable named nix-shell not found on path

2. Invalid option '--internal-re-exec-version=2.1.3'

When building with stack --nix build on this branch, I encounter the following error:

cardano-wallet > <no location info>: error:
cardano-wallet >     <command line>: can't load .so/.DLL for: /home/jonathan/.stack/snapshots/x86_64-linux/39114b4d1b2947620b59a8803c2d63ab84dbed136609fe44ef27b38ba074c955/8.6.5/lib/x86_64-linux-ghc-8.6.5/libHSlibsystemd-journal-1.4.4-8tyUPpbVTnv5SGCSb8krtm-ghc8.6.5.so (libsystemd.so.0: cannot open shared object file: No such file or directory)
cardano-wallet >                      

Building with stack build (without the --nix part) still works fine.

I get

normal stack build works. But this also happens on master.

@jonathanknowles I suspect you have deleted some /nix/store paths after building the stack snapshot. Could you run:

ldd /home/jonathan/.stack/snapshots/x86_64-linux/39114b4d1b2947620b59a8803c2d63ab84dbed136609fe44ef27b38ba074c955/8.6.5/lib/x86_64-linux-ghc-8.6.5/libHSlibsystemd-journal-1.4.4-8tyUPpbVTnv5SGCSb8krtm-ghc8.6.5.so | grep libsystemd.so

and check that the listed file exists?

@hasufell That output appears to be from nix < 1.12, which is a very old version. Here are some instructions for installing and configuring nix for IOHK projects: nix.md.
