It is possible to exfiltrate a file descriptor out of the build sandbox of FODs, and use it to modify the store path after it has been registered. To avoid that issue, don't register the output of the build, but a copy of it (that will be free of any leaked file descriptor). Test that we can't leverage abstract unix domain sockets to leak file descriptors out of the sandbox and modify the path after it has been registered.
