Unable to initialize compiler: lstat /build: no such file or directory

[ingenieroariel]

Describe the bug
keto serve does not start

To Reproduce

1. keto serve
   Unable to initialize compiler: lstat /build: no such file or directory

Expected behavior
The server running

Version:

• Environment: [Nixos]
• Version [7798442]

Additional context
I am writing a nixos service for ORY, was already successful in creating one for Hydra and Oathkeeper but ran into this, that looks like #73

I was able to avoid the segfault by replacing the relative url with an absolute one in my system.

I could not get packr to work on nix, but this workaround stops keto serve from dying early in the process.
