Subject: [PATCH] nix(loadtest): allow running multiple postgrest-loadtest in
 same working directory

There is no need to store the out-links to the various build artifacts
in the current working directory while running postgrest-with-pg, which
is used by postgrest-loadtest. Instead reference the nix store paths
directly.

Resolves #5028
