Punt on improper global flags for now

Browse source 
See the note in the test.

We don't want these flags showing up for commands where they are
irrelevant.

Eventually, this needs a proper fix, but it need not be a blocker for
stabilize: for a quick-n-dirty punt, just put these flags behind the
`nix-command` unstable feature.

This is fine because they are only relevant for commands which we don't
need to stabilize for a while.
