Andrey Devyatkin a67ba5536d Fix #3281: Unexpected result when using build args with default values ...

Fix the issue when build arg is set to None instead of empty string. Usecase:

cat docker-compose.yml
  .... args:
  - http_proxy
  - https_proxy
  - no_proxy

If http_proxy, https_proxy, no_proxy environment variables are not defined then http_proxy,
https_proxy, no_proxy build args will be set to string None which breaks all downloads

With this change undefined build args will be set to empty string instead of string None
