Is this one related or is it a bug left from before?

Not strictly NixOS-specific, and certainly reasonable to separate out into a different PR to be individually evaluated. While debugging, it came up that buildkit (or at least, the version shipped in NixOS 21.11) has a --rootless which is documented to enable configuration changes for better compatibility with rootlesskit -- but that said, I didn't go back after getting other issues ironed out to confirm that we were unable to run tests without it.
I'll do that now and follow up with findings.

Could you give some info about this line? Thx.

Sure. NixOS doesn't have a /bin/bash; the only executables with hardcoded locations are /bin/sh and /usr/bin/env; everything else comes from a generated PATH with pointers into /nix/store/<hash>-<application>-<version>/bin (allowing NixOS to have different versions of the same application, or differently-compiled versions of the same application version, simultaneously installed; similarly, dynamic library linkage all uses explicit rpaths with a hash component, so applications only link the specific library versions they were compiled and tested against, even if some newer or differently-patched version of the library is installed for a different application's use).
Using #!/usr/bin/env bash causes a PATH lookup to be used to find the shell interpreter.
Lets folks on NixOS (or other Linux distros with Nix installed on top) run
./scripts/testby first runningnix-shellornix-developto enter an environment with a Go compiler, buildkit, rootlesskit, and runc in their PATH.
