Brian Goff 5e4444823c build: only use env for args if set
When following this pattern:

  buildx build --arg FOO

Where we want to pull `FOO` from env, currently we always set `FOO`
regardless if the `FOO` env var is even set.

This change makes it so that `FOO` would only be set if it has been set
in the env (even if it is set to empty).
