Revert "[check] gn gen --check -> gn gen --check=system"

This reverts commit 08f0b15d72c8c5479ede74ab671bbea105ca5750.

Reason for revert:

Oops, I missed some --check=system in bringup that the recipe side is failing on, so I'm going to revert this until I fix those because otherwise people won't be able to fx set some bringup configs in the meantime.

Original change's description:
> [check] gn gen --check -> gn gen --check=system
> 
> Be stricter.
> See: `gn help check`
> See: https://fuchsia-review.googlesource.com/c/infra/recipes/+/404874
