Issue description

Describe your problem

running make pg_test fails, with an error. I posted the complete output in my terminal below, I think the root error is :

docker-compose build golang ubuntu s3 pg pg_build_docker_prefix
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/urllib3/connectionpool.py", line 699, in urlopen
    httplib_response = self._make_request(
  [stack trace ...]
  File "/usr/lib/python3/dist-packages/docker/transport/unixconn.py", line 30, in connect
    sock.connect(self.unix_socket)
PermissionError: [Errno 13] Permission denied

Please provide steps to reproduce

run make pg_test from the root of the repository.

note: I was trying to test my pull request #1379 (the one which introduces USE_BROTLI), the output below is what I got when not setting that opton,
but setting USE_BROTLI=1 reaches the exact same error.

Please add config and wal-g stdout/stderr logs for debug purpose

If you can, provide logs

running docker-compose build golang ubuntu s3 pg pg_build_docker_prefix from my command line triggers the very same error
